Experiments with world choropleth map using Leaflet and GeoJSON.

See http://tetrahedra.co.uk/worldmap for an example.

Based on tutorial from http://leafletjs.com/examples/choropleth.html

Original GeoJSON with world countries from https://github.com/johan/world.geo.json/blob/master/countries.geo.json Unfortunately this uses 3-letter ISO country codes so had to be converted to 2-letter using http://en.wikipedia.org/wiki/ISO_3166-1

All aid data from DFID IATI data at http://iatiregistry.org and from Aid Information Platform http://aipbeta.dfid.gov.uk

##Install## Install folder on any web server. Navigate to /index.html to see the map.

##Files## ###index.html### Contains main js for initiating the map, referencing the data files
