After fiding out Gephi I came across hive plots, which seem to be genuine way to plot large networks with information gain in mind. The tool is called linnet, which probably relates to "linearizing the network" and was developed in the group of Martin Krzywinski. Bellow is a plot from their webpage, while you can find more detailes in talks and posters that are linked on their website. Cool stuff indeed!!! They also have a tool called circo for circular display of relations among many nodes, something like correlations.
