With the latest update to the CDC recommendations for international travel (trdr: don't), I wanted to visualize the stats of different countries. I found this neat little webapp that lets you interactively assign colors, export the data as JSON and then build a static PNG:

More Underground Maps

Andrew Godwin has just released an excellent mapping project, visualizing a few London Underground stations, complete with public corridors, escalators, spiral staircases and platforms.

Poking around his other work, the Twin Tubes map is also worth a look - the underground network with each individual track visualized.
