By programmatically I just mean passing coordinates to a function like
graph-draw. But does graph_draw() accept z coordinates, or only (x,y)
coordinates? I assume it is only (x,y) since you say that graph-tool does
not have 3D visualization. I suppose I could write code to project a 3d
set of nodes onto a 2d plane, and then alter node sizes to add the effect
of perspective. But I am hoping to find a program that does this natively
and quickly for large graphs.
Thanks again!
