Kartograph mapping framework
My now discontinued mapping-framework, based on jQuery and Raphael.js. I worked on Kartograph at a time where d3.geo was still in its infancy, and mapshaper was a closed-source Flash application. Also I had to support crappy Internet Explorer versions without SVG support.
Kartograph used SVG as map container format, but preserved the projection in a special <proj>
tag under <defs>
.
