GraphPlotter Revisited

This is my second attempt on writing some piece of software that can visualize graph structures.
My first attempt was quite messy so this time around I'm using a force-directed layout algorithm for some good "layouting" of the graph. Graph Plotter 2.0 is definitively an improvement if you ask me :)

Note if you wanna try it out, that the graph is represented as a file, where the first line contains the number of nodes and each remaining line defines an edge.
For example.
