to have fast algorithms to layout the elements is very good, but a visualization that opens in 1 second but that I cannot touch is useless. I tried to open a name cloud visualization on a group with 21300 elements, the visulization take just few seconds to open up but than even to display a popup window with a mouse over an element take seconds. Not to mention that I cannot scroll the view or I have to wait minutes sometimes.

n log(n) sounds quite good for this kind of algorithm. But, what does n mean? Is it the amount of nodes, or the amount of edges as well?
