very cool. Made something with a similar idea, but using timelines instead of maps. I wonder if the two could be combined in some way

Comparing timelines is an awesome idea, understanding when certain events happened in relation to others is really interesting. Maybe even overlaid in different colors or something instead of separate timelines.
Here's the repo btw: https://github.com/MichaelMilstead/timeline-of-everything
