From Delaunay edges to spatial points

federico vaggi-2

I am a relative newbie to tessellation, so I might be asking a very naive question.  I have an unweighted graph (list of nodes, edge lists) that I would like to plot on the surface of a sphere.

Given the edge list, is there a way to come up with a x,y,z position of all the nodes so that they follow a Delaunay tessellation?  Most software I've seen starts from positions in space and then tries to obtain the edge list - I'd like to do the inverse, if possible.

I am not 100% sure if this is more appropriate for the scipy mailing list or the networkx mailing list, so I think I'll post it in both places as long as that's not frowned upon.

Thank you very much,
