Leaflet is an open-source JavaScript library for mobile-friendly interactive maps. Weighing just about 38 KB of JS, it has all the mapping features most developers ever need.
Leaflet is designed to be simple, yet effective, to be compatible with all major browsers and to support plugins in order to extend its functionality.
With Leaflet you can easily assign custom map markers, create choropleth maps or even non-geographical maps.
