I asked on reddit here about what map library I should use a few weeks ago: https://www.reddit.com/r/Frontend/comments/zutb4l/recommendationadvice_for_embeddable_maps/

I started off thinking I would use Google maps, but then pivoted to Leaflet. I really liked Leaflet in the end, easy to get started with and enough StackOverflow answers that I could figure out how to get it to behave how I wanted. If you have any specific questions about the code, DM me.

It's my first time doing any development with a map, but I would use Leaflet again for sure.
