You can use the Java2D classes to draw things. I would imagine you need to come up with an algorithm that creates a layout for all the vertices such that there is minimum overlap of the edges, and then just connect the dots.

It's quite a fascinating problem to find (x,y) coordinates (in 2D space) for the vertexes such that none of the edges cross each other. (if such a configuration exists).
