How to programmatically draw arcs between cities on a global map?

Question

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).

Answer 1

From your description, any language would do. Java, Python, C# etc. They each have graphics libraries that make it easy to draw lines and text and output images.

Answer 2

Ah, found one that will work perfectly myself.
