Wikipedia has a number of cool, interactive SVGs. This illustration of satelite orbits is my personal favourite: https://upload.wikimedia.org/wikipedia/commons/b/b4/Comparis...

I didn't know this either! I once made an interactive dashboard and couldn't figure out how to add an on-click action to my SVG heat map. So I used the same coordinates that I used for the heat map to make a bunch of invisible divs on top of the SVG, and added on-click actions to those divs.

Yes, this was interesting to learn.

On a tangent: it's awe-inspiring just how much older the Egyptian pyramids are, vis-a-vis the other pyramidal structures listed there.

Transamerica Pyramid : lol
