I'm looking for ready-made libraries or functions that make graphs that are similar to the ones in the video game Winning Eleven (or Pro Evolution Soccer in N.America):

(The six-sided graph in the middle of the picture in the link above)
Alternatively I can build it from scratch using GD library. Is there anything I should be aware of?
Any help or advice is appreciated.
