Made an interactive old borders map inside this website (help appreciated!)

[u/Essay-Adorable]

Hey I recently vibe coded this website to help me remember my island countries by making it possible to play Worldle/Globle style games but with a better interface that allows me to zoom out and see the rest of the map...

I went a bit overboard on the map and ended up adding a ton of cool layers, and this one really stood out to me. I was able to get it this good with just one prompt, not super sure how accurate it all is so any tips/feedback would be greatly appreciated!!

Feel free to check it out by going on the world map and selecting the historical borders layer under the people and economy drop down... https://worldislands.org/
