Thematic maps describe statistical data about places. They come in many flavors: color-coded regions, area-scaled circles, pie charts, flow charts, heatmaps, and so on. By aligning statistical data to a geographic anchor, the underlying data can be made easier to understand.
Cartographer.js, a simple library for Google Maps that simplifies the development process and provides instant access to proven visualization techniques. Developers are freed from worrying about how to tweak the Google Maps API to build the thematic elements they need, and can focus on more important problems like data collection and normalization. Cartographer.js supports custom styling so it can integrate seamlessly into existing web applications.
How do I use it?
Cartographer.js is a simple one-line include. It relies on the excellent Raphael.js vector-graphics library. Cartographer.js is currently in an early-stage Alpha release.
You can find out more by visiting the Cartographer.js website, where you can download the script, see examples, and read through the documentation.
