Kartograph is a new framework for building interactive map applications without Google Maps or any other mapping service. It was created with the needs of designers and data journalists in mind.The core concept of Kartograph is to separate the mapping process in the map generation and map rendering part. The client-side library kartograph.js renders pre-generated maps stored in SVG files. You can chose among hundreds of ready-to-use maps or simply generate your own using kartograph.py, the open source Python SVG map generator.
