Hi Esa,
We will probably not document that particular chart type, since we use
it internally and we want to keep the freedom to change it whenever we
need to without causing inconvenience to external users. However,
there is a similar documented chart type that you can use to draw map
pins:
http://groups.google.com/group/google-chart-api/web/chart-types-for-map-pins
You can only draw one pin at a time, but you have more flexibility in
what pins to obtain. Also, if you want 11 pins, like in the sprite,
you just need to give 11 different Chart URLs.
Hope this helps!
Roger
