I have a series of cities that I need to programmaticly draw arcs between on a global map. The arcs also have to be labeled with a series of values. Output needs to be png or something similar (i.e. I am not looking for a javascript solution.)
Any suggestions on ways of doing this? I can choose language or tool (so long as it is free).
Ah, found one that will work perfectly myself.
