Show HN: How many libraries are a walk away?

In the course of other matters, I found myself wondering how many places around the world one can walk to the library from. So I compiled a list of all the libraries in OSM, plus officially listed ones in China and Mexico, and then ran that through mapbox’s isochrones api to see.

Naturally to some extent this follows population density and gdp, but there are quite a few interesting places - Kerala for example has a phenomenal number of libraries!
