Thematic Mapping API enables you to create powerful maps with a few
lines of JavaScript. The API will be free to use on non-commercial
sites.

The file contains the Thematic Mapping API (tmapi-0.1.js) and an
example file with geometry data (worldborders.js).
I'm currently working on the documentation. The examples will help you
to get started:
