I have a college assignment, where I have to draw diagrams of voronoi, delaunay, minimum spanning tree etc for the college. I want to do that in computer. I searched in google with no luck. Is there any good graph drawing software you are aware of?

There is Graphviz. It can be tedious at times, but it's very flexible.

For simple "hand drawn" stuff, I use Inkscape for everything.
