Hi, I need to compute the voronoi diagram of a set of points in R^n.
I'm quite unschooled on the topic, could someone point me to the right references so that I can 
a) understand the theory behind it
b) implement an actual algorithm to compute it 

PS. Googling I found out I need to know about euclidean graphs, but I couldn't find any decent introduction to it. Pointers are appreciated!
