Read it on first pass as "Neanderthals," didn't rescan until I hit "Roads & Railroads"!

This looks nice. I'd like to see a rendition for each United State (and for other hominids!) but taking a quick peek at the source this looks closely tied to specific NL data sources/schemas.

Thanks! Yeah, getting the right data is challenging, but other than that it’s doable reusing a lot of the current rendering code.
