Show HN: Animated map of US railroad and population growth

https://app.honeycombmaps.com/shared/UoeChOqwxXf3fI2PxKXRBmh_RHW-3UVa

This map shows population of each US county over time, from the US census. It also shows the US rail network over time, with data from Jeremy Atack at Vanderbilt. I think it's interesting to see the interdependence between them. And the fact that the US rail network was substantially complete by 1900.
