Show HN: Shareable maps with data encoded in the URL

Hi HN, I built a tool to create minimalistic vector maps online, and generate a URL with the entire dataset as query params.

The URLs generated are off-putting, but in turn you get private shareable maps.

The code for the website is also open source and lives at https://github.com/ironmaps/mapinurl/ .

Please let me know if you have any usecases I could solve for.
