A new opensource framework for mapping is on my radar today. It’s called Kartograph, and it is still in the early stages of development by Gregor Aisch (@driven_by_data). From the website:
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.
You’ve definitely got to check this out, even if it is just to gaze in awe at the examples that he has posted.
Thanks to @sgillies for tweeting about it.
