Cartographer: Thematic Mapping For Google Maps
Thematic maps are very useful when describing statistical data about places. The data, simply, becomes much easier to understand.
It supports 3 visualizing types:
- Chloropleth (color coded regions)
- Pie charts
- Point clusters
The areas on maps are mentioned as latitudes or regions (depending on the type) which means no hacking or manual calculations.
Every visualization type comes with different options like colors, opacity, stroke & more.
P.S. The library is currently on alpha state but pretty solid.
