India GIS Map with Leaflet

We will use Leaflet.js to make a map of India. This uses a GeoJSON dataset for India which has been simplified using The states for Telangana and Andhra Pradesh appear separate. J&K is as per India official position. There are nice pop-overs for state names.

This is the GeoJSON File. The Zone property is used to shade the states. You can download it as a zip file here. Only a snippet is presented below

var india_geo = [{ "type":"Feature", "properties":{ "Zone":2, "ST_NM":"Andaman & Nicobar Island"}, "geometry":{ "type":"MultiPolygon", "coordinates":[[[ [93.84861388352397,7.240511941073294], [93.73864250664644,7.190689919704084], [93.69123542847228,7.19085093252454], [93.65621511573505,7.126739829579492], [93.67784740013747,7.016118856200308], [93.74676860258899,6.961872622723433] ]]] } }]

While exporting the geojson from QGIS, I had certain issues about the validity of the file, specifically Right-hand rule. That was fixed using Mapster. Further the QGIS output had a FeatureCollection top level group which I deleted to decrease nesting level in the GeoJSON file.
