Interactive Maps with Leaflet

Learning web mapping using Leaflet

From the Leaflet website:

Leaflet is the leading open-source JavaScript library for mobile-friendly interactive maps. Weighing just about 33 KB of JS, it has all the mapping features most developers ever need.

These maps let you select a base layer, and interact with two different choropleth maps of the US.

1. An interactive map of the US Population Density - cloned from the Leaflet tutorial on Choropleth Maps
2. A second overlay that shows the Renewable Portfolios of the US States. This was inspired by the data published by NCSL here.
