Because it's using a graph layout algorithm called Force Directed Graph Drawing, where you basically connect the nodes together with springs and then run a simulation. The algorithm's really simple and works pretty well, but unfortunately it doesn't really have the concept of 'finished' --- you just keep simulating until it looks right. Some implementations watch for small deltas and when the change rate gets low they stop the simulation, but it can take a while and people frequently don't bother. |
