Happy Paul Bunyan Day! (43/365)

Posted on by

Happy Paul Bunyan Day!

Paul Bunyan is a Minnesota (and northwoods) legend. He carved the Grand Canyon with his glorious ax. And Babe the Blue Ox? Well…

Today’s map offers places named after Paul Bunyan that you can visit to celebrate this wonderful day! 😉Paul Bunyan Resort on a map.View the Map Here.

Original prompt

Hi there. I’d like to make an interactive Paul Bunyan map to celebrate Paul Bunyan Day. I have created a Mapbox basemap in Cartogram and have the API token to use it. I would like to use that basemap. It’s a Lambert Conformal or Equal area projection. I forget, but it’s centered on the US.

I also have a geojson dataset of places named after Paul Bunyan or Babe the Blue Ox. I would like to make the map fun and somewhat folksy.

Please use a cool, folksy font that hovers over the map in the upper-left-hand part of the map.

Title Ideas: “Place to Celebrate Paul Bunyan Day!”

When a user clicks on one of these spots, please have a tool-tip pop up that gives the name of the place, the type of place (I forget which field this is but there is one), it’s city and state/province, and a little button that says: “Take me there.” When the user clicks this button, the default map application on a mobile device or computer should open (e.g., Apple Maps, Google Maps, etc.).

Do not have arrows connecting the tool-tip/info window to the point. Use rounded rectangles 4px max for all borders and windows, etc. Do not put any background rectangle behind the title. In the lower right have a hamburger menu button. When the user clicks it, please provide attribution for Mapbox (for tiles and design), Turbo-overpass.eu (for data), and Minnesota for being the Paul Bunyan state. Also, add a “Provenance Doc”, which will link to your provenance JSON when our conversation is done. You don’t have to produce that document until the final package is exported as a zip file.

Below is the cleaned dataset. If you can save it as a separate .geojson file in the export or just load it in the JS/HTML files directly, that would be awesome.

World Cancer Day (35/365)

It’s World Cancer Day.

I decided to create a global map of the leading cause of death by cancer for males and females by country. The data was collected and cleaned using Dataset Doctor GPT. Map created with Web Mapper GPT.

Web Mapper GPT Prompt

I would like to make a map highlighting the leading cause of death by cancer in each country with data in the attached dataset. This will be for International Cancer Research Day. It should be a serious map, minimalist with a journalistic feel. Quite simple. On desktop, I would like a donut chart showing the number of deaths caused by each type of cancer world wide. Any that fall beneath 8% of total deaths should be included in an “Other Cancer” category. When the user clicks on a country (equal earth projection, please) I would like a pop-up to display showing country name and leading cause cancer cause of death, as well as any death numbers and a source in the popup if possible. Please us a dark background. Color each country by the type of cancer that leads in that country. Up to seven unique colors. The eighth color (if necessary, as I don’t know how many unique types of cancer are in the dataset) should be a gray that represents “Other Type of Cancer”. It will displayed if a user clicks on that country. Countries without data should not be filled in. If possible, since I don’t believe the CSV has geometry, can you link this dataset to a polygon boundaries dataset of countries (e.g., Natural Earth Data?) so it can be a category by color map? Thank you!

 

Dataset Doctor GPT Prompt

Please create a global dataset that provides the type of cancer leading to the most deaths in each country of the world (for which there is data). I’m not sure where this data might live: perhaps the WHO, UN, World Bank, or elsewhere. Please scour high or low. Any data within the past 20 years can be included. If the dataset does not yet have geometry, or is compiled from a bunch of different sources, I would like to link it to Natural Earth data, so please include or add a field that makes it easily joinable. Field examples that would be useful: – Country Name (English) – Most common cancer leading to death (broad categories, simplified… e.g., Lymphoma, not particular types of Lymphoma, etc.) – Count of deaths from this cancer (when available), null if not – Country population estimate (perhaps in Natural Earth data already) – Per Capita GDP (or similar economic indicator data just for context) – any other field data you find relevant – please include ISO country codes too. Thanks! – source – year or years for data Thanks!

Missing Persons Day (34/365)

Posted on by

On a serious note: it’s National Missing Persons Day.

The United States has a serious problem. People go missing… a lot. And they are often never found. Complicating matters, the FBI reports on national missing persons statistics, but it doesn’t report state-by-state.

Many states create annual reports of missing persons, but they use different statistics and standards. Some differentiate between minors and adults. Others do not.

I asked Dataset Doctor GPT to scour the web for all state reports it could find and create a (semi-) comprehensive state-by-state dataset. It took a while… but after checking in on it a few times, it finally assured me it found all that it could. (I had it search in batches.)

I then asked my other handy GPT agent, Web Mapper GPT, to map the data.

Dataset Doctor GPT Prompt

Hi, for national missing persons day, I would like to create a state-by-state dataset of missing person reports. I’ve heard the FBI has a lot of records and there are other public records. The map the dataset will be used for will primarily be designed to build awareness about missing persons and have a rhetorical / empathetic affect, not data exploration or analysis. I envision having statistics such as adults versus juveniles missing, as well as a filter that allows people to view state totals compared to one another using proportional symbols: either adults only, juveniles only, or totals. My ask from you: can you search the web for good sources where I can download or scrape together such a dataset, please? If there is a dataset available, please create a geojson with geometry or shapefile. Clean the dataset to show only State Name, Data Source, relevant counts to my needs, percentages, and any other relevant information to missing persons (e.g., year). The more recent the dataset the better, but anything within the past few years is fine. Thank you! Please report back with existing datasets you have found or places where you think you or I may be able to piecemeal together a dataset to help make this map. I’ll give further instructions from there. Much appreciated!

Web Mapper GPT Prompt

Hi there, I would like to make a national map of missing persons. I have a schema, dataset, and a text file of things to consider and a title for the map. can you help create this for me? Note: it should be mobile first. It should all fit within the window of a mobile device or desktop. The design layout should adapt appropriately depending on the device being used to view the map: e.g., bottom pane info windows for mobile, pop-up mobile windows on desktop, etc. I would love for each state to be symbolized by a donut chart. The donut chart should be proporionately sized by radius on the total number of missing people reported. Then, the donut chart itself should show Juvenile (or up to 18 year olds) missing and Adults 18 and older missing (or similar). There can be an other category too if that is required in some cases. States without data should be represented by a circle symbol that appears like a hole through the base map (e.g., a white background in the middle. A punched hole effect in the basemap. When a user hovers or clicks on the hole, a note about not all states report missinng persons data, and a comment about how missing data means they cannot be found, etc. (See schema and attached notes). Please project the United States using Albers Equal Area or Lambert Conformal if possible. Include Alaska and Hawaii if they have data. If they don’t, exclude both from the map. Thank you.

Happy Groundhog Day! (33/365)

Happy Groundhog Day!

I’ve never been that into Punxsutawney Phil’s special day. I always doubt his wisdom. So I thought I would go to iNaturalist and download every sighting of a groundhog in Pennsylvania since January 1, 2021, so we can ask them what they think. The best part… the pop-ups have pictures. They really are cute rodents — even if they are crap at predicting weather patterns. 🙂

Web Mapper GPT Prompt

Hi, I need to make one more map today. I’d like to make a map for Goundhog Day.

I have an iNaturalist dataset of ground hog observations in the US and Canada. Can you, using an Esri or other open topographic or natural landcover base map create a cute little map with every one of these sightings?

There are a lot, so I’m not sure if it’s best if this is loaded as a CSV or a geojson or what? If it’s not possible to load this data easily, perhaps I can create a similar map that is only the state of Pennsylvania (just 2800 or so sightings). I have a separate dataset for this if that is better.

The map should be funky, like the groundhog day event!

Please come up with three witty titles regarding how… if Puxatawny Phil its own shadow, well, we can always ask another one. Or Best of Seven…? etc. Something witty.

Please design the map to have similar fonts (feel free to use Google fonts) as the website here: https://www.groundhog.org/. Same color scheme too for accenting, etc. (It’s not exactly color blind friendly, so don’t use thse colors to differentiate values).

Finally, please create a little groundhog silhoutte icon, SVG for leaflet, or PNG for stacks, that is green or blue. A little drop shadow, very light, would help.

Thanks! If you use clustering, and I assume you will need to, please use a larger version of the silhouette as the cluster symbol.

Finally, don’t let the user zoom out to show more than 5 degrees in any direction past the the range of data. Also, in a hamburger menu, please add a year filter, with each year listed and an “All Years” reset button. Also add a sources button please. The sources Modal should begin closed no matter what and close when someone clicks outside of it.

Happy World Hijab Day!

Around the world there are meetings and get-togethers, as well as a free online conference for people to celebrate the hijab. You can learn more about the online celebration and local chapter meetings and support here: https://worldhijabday.com.

This map shows all the countries in the world that have World Hijab Day Ambassadors appointed. You can find and contact them on the official website. I thought the spatial distribution of official ambassadors would be interesting. I added information about each country’s predominant religion and type of government too, just to add some interesting contextual elements.

For those who celebrate, Happy World Hijab Day!

Happy Hot Chocolate Day!

It’s been a chilly January in much of the United States. Pretty standard for Minnesota, where we often reach -30-degrees C in December, January, and even February, but still…

I was pumped to see this National Day on the calendar. It got me thinking… Is hot chocolate even a thing across the entire US?

Let’s find out…

Can you create a spatial dataset of the average daily temperature by US county OR, if not county data is not available, by US state on January 31 or, if that date is too specific, in January broadly.(Whatever averages you find, e.g., past 10 years, past 20 years, past 50 years, etc., whatever is easiest to fetch is fine and it doesn’t have to be current… any dataset within the past 20 years containing this info is fine. I’m going to use this information to create a silly map about how likely National Hot Chocolate Day is to be celebrated across the US on January 31. Fields needed in dataset (if county data isn’t possible to collect, skip county-based fields listed below, no worries): – County Name – State Name – County Avg Temperature – State Avg Temperature – State FIPS – County FIPS – Data source: Name I would love this in exported as a shapefile or geojson format with geometry from Natural Earth Data if possible. Otherwise, a CSV file with the data is fine as well. I can join it to a spatial dataset later. Thank you!

Hi. I would like to create a friendly, atmospheric, and chocolately looking map of the United States in an Albers equal area projection (for the contiguous US, I don’t care what Alaska and Hawaii projections are used, but those two states should be insets) of hot chocolate consumption. I have a GeoJSON dataset of all the states with geometries, and their average January temperatures. Please create a five-class breakdown on the temperature field, and use a brown color value to display, in choroplethic fashion, which states are most likely to celebrate National Hot Chocolate Day on January 31 based on average temperature. Have a small legend that labels each classification. The legend title should be: “Likely to celebrate?” Category titles from highest temperature average to lowest temperature average: – Not at all – Could be persuaded – Why not? – You betcha! – Two or three cups minimum!!! When a user clicks on a state, show the state name and the average temperature value for that state in Fahrenheit. Aesthetically, the map should have chocolately brown themes, and the oceans should have some graphic design marshmallow like icons looking like they are floating (e.g., partially submerged). Put about 5-8 of them in the Pacific Ocean, 4-7 in the Atlantic, and about three in the Gulf of Mexico. They don’t resize or change. The entire US should appear in the window. There should be no “below the fold” everything should fit in the window. The title of the map (upper-left) should be across the top and read: Happy Hot Chocolate Day, 2025! Subtitle: Which states are likely to celebrate based on average January temperatures? Upper-right: hamburger menu. when opened: Sources: NOAA, Dataset Doctor, Web Mapper GPT, and any other attribution that may be required from the software stack used. Clicking anywhere outside of this window automatically closes it. Important: make sure this window/modal/panel is closed when the map opens. Thanks! On mobile devices, ask the user to tilt the phone to landscape before viewing the map. Then, when tilted, ensure the map fills the window above the fold (and also without the title interfering with interacting with the map. Thanks! Use Google Fonts to create a warm, inviting, hot chocolately over the top camp fire vibe. 🙂

Happy Martyr’s Day! (30/365)

Posted on by

Happy Martyr’s Day! It’s a national day in India celebrating Mahatma Gandhi.

To honor his legacy, I created a map of his historic march with information along the way at each stop. Again, doing one of these a day in my spare time doesn’t leave much time for innovation or design, but I can imagine coming back to this and adding non-proprietary imagery and details along the way.

Also, this is my first ever map in Hindi. There is a button in the upper right. You can switch between English and Hindi there. I cannot vouch for the Hindi translations, but I assure you, they are better and more accurate than what I would have been able to do before prompt cartography. I hope they serve this great human being justice.

Map production time constraints and language barriers aside, Gandhi inspires me (particularly in today’s geopolitical climate here in Minnesota).

I am proud to give Martyr’s Day a map of its own in our #365DaysOfMaps challenge.

I would like to make a map of Ghandi’s travels for India’s National Martyr Day. I have a CSV dataset (attached). Please keep this map pinned to India and Bangladesh area — i.e., cannot pan out of these bounds or zoom out past South Asia. Please use a topographic base map and if possible use a mask that that has India’s flag colors lightly embued in it to give it an India vibe. The mask must be below the mapped data, but abover the base map. Please use point symbols that are in India’s Orange color (on the nation’s flag, with India’s Green slight drop shadows. When a user clicks on a point, a pop-up info window should appear showing all th English information such in the following visual hierarchy order: – Stop Name (Place Name) and Province – Description – Context (when available) – Date (near top but subdued) – Sources (as a bulleted list) Please use an aesthetic and palette that ties to India’s national colors. Keep is subdued. The title should be Display Text in the format of 1950s Newspaper Headlines. Come up with three good titles dealing with Martyr Day and Ghandi. perhap something akin to “The Martyr’s March”. Pick your favorite and include it in the upper-left hovering over the map in large, print-map like style. No background box. (Make sure you use some effects to make it legible over the base map, e.g. drop shadow, etc.). Make the title stand out. In the upper-right, include a hamburger icon that when clicked shows a menu that includes a link to Sources. When that is clicked show a modal splash window with sources and attributions. It should close when someone clicks anywhere outside of it and it must not be open when the map opens. Also include a button that says “Hindi” in Hindi, please. When the user clicks this button, the map pop-ups and title and hamburger menu items all switch to Hindi. (There are Hindi fields in the dataset replicating English fields. Switch them in the popups, please.) The menu item the user clicked that said Hindi (in Hindi) now says English (in English). If the user clicks this, everything switches back to English, including the pop-up windows on the map.

Happy National Jigsaw Puzzle Day!

As the weather hit -30-degrees C here in the Free State of Minnesota this past week, I was thrilled to see this day arriving soon. Puzzles are how we socialize without talking in the winter in these parts during the winter.

This was the fastest “map” I’ve created yet this year. Took about five minutes to get it working. I used regular ol’ ChatGPT to create the puzzle maps using screen grabs from Open Street Maps (and Contributors) website.

Maybe you’ll recognize some of the places. Maybe you won’t. Have fun!

Hi, I would like to make a puzzle out of this Ope Street Map image I have for International Jigsaw Day. Could you create a simple website for me that does the following: – When a user visits the site, they will see this image broken up into a variety of scattered jigsaw pieces on a faux wood background. The pieces will be scattered and not necessarily oriented correctly — though all face-side up. On the table will be an outline of the size and location of the rectangle map area they must fill in with the pieces. They will then select pieces and drag them to the correct spot. They may rotate pieces by right-clicking or left-clicking with the Alt key pressed down and pulling up or down. All pieces begin in random 45-degree orientations. Rotations move in 45-degree increments when users rotate. It must be possible to align all pieces correctly to eventually fit. The pieces of the map should be roughly equal height and width. Use standard jigsaw cuts. Try to make them unique enough to allow a user to discern when pieces go together by looking at the cuts. But some duplicate cuts are permitted. Please make the puzzle 25 – 40 pieces. Whatever works best for the image and layout. On mobile devices, ask the user to rotate their phone before beginning. Ensure that the puzzle feature is above the fold when the mobile device rotates and gets resituated in the browser window. There should be a simple title under the pieces but when the puzzle is finished above the puzzle: Happy Jigsaw Puzzle Day! Elsewhere on the site, perhaps in the lower-right or upper-right, you decide, there should be a hamburger menu. When clicked, a small pop-up shows bulleted: (https://openstreetmap.org) and [ChatGPT](https://www.chatgpt.com) – For [#365DaysOfMaps](https://mapdesign.icaci.org) – Source: Open Street Maps, OSM, and Contributors, 2026. – Specific map scene available [here](https://www.openstreetmap.org/#map=14/50.08042/8.24172)

National Hug Day (21/365)

Posted on by

Happy National Hug Day.

My family loves hugs. But I know a lot of people that don’t really enjoy them. Some people prefer light kisses on the cheeks, handshakes, fist bumps, or back pats. One’s preferences are definitely cultural and perhaps even genetic…

So I thought it would be a good idea to create map for National Hug Day that highlights where you can celebrate hug day more openly versus where you may want to be more cautious.

This is based on ample evidence collected in many scientific studies but it is not legal advice. Please advise with legal counsel before trusting this map.

Enjoy Hug Day!

United States Map of HugsView map here.

Original Prompt

I need to come up with an idea for National Hugging Day. I was thinking of something cynical, like showing states where hugging without permission is a misdemeanor offense or assault.

Is there any generic information on where hugging, by state law, is more likely to get one cited or arrested than other places? If not, please come up with five good (and very simple, qualitative) map ideas to create for National Hugging Day, please. Thank you!

I would like to make a map of penguins in antarctica using a south pole projection. It doesn’t have to be particularly dynamic — it can be a static orthographic or stereographic view of the south pole. I have the datasets — uploaded now. Please tell me: which stack and mapping agent will be best for showing the south pole? It doesn’t have to be a “globe” renderer if there is one that can show Antarctica from a flat polar projection on the screen. Please come up with three solutions, with pros and cons for each. Thanks!
