The above image contains almost 100.000 nodes, extracted from my Twitter relationships (transitively, of course, I’m not the Lady Gaga of social networking, after all…! 😉
The above image was obtained by allowing Gephi to execute its Force Atlas 3D layout for about an hour, with two threads of execution.
The below image, of the same 100.000 node dataset, was obtained by allowing Gephi to execute overnight, with 200 threads running on my 4 core machine (which pretty much made my computer totally unresponsive during the processing…). But the end result is amazing:
Below, still the same dataset, but now a slight zoom-in, and node labels activated. At this level of zoom, Gephi makes it very easy to analyze the network visually, it’s very easy to move around the large graph, panning and zooming etc – the layout algoritm is very impressive – I’m definitely going to donate some $’s to the Gephi folks on their website, Gephi is an amazing piece of software!
