Google has added a map chart type to its free data visualisation solution. Google charts API creates images on the fly to present data encoded in the image url.
The available maps are at continental or world scale, with the exception of the USA where geographical data for each state can be displayed.
Data for the charts is included as url parameters using ISO Country Codes, RGB color values and simple numeric or string encoding of data values.
The URL’s are simple enough to construct by (a careful) hand, but are more suited to scripting and code generation.
