In different graph packages, there will be completely different layout
algorithms. For example, Cytoscape has force-directed layouts such as
Organic, Prefuse, Force, Spring, and Inverted Self Organizing Map (SOM).
Where do you start? Sometimes you should try them all!

the different results on the channel-flip data.

This shows Cytoscape's layout of the television channel
browsing data using Organic, Prefuse, and Spring layouts
In all these layouts, it is apparent that there is one large densely connected
cluster, with a number of more weakly connected channels around the
center. The big difference between the defaults in these algorithms seems to
be the density of the center of the clusters and how far spread out some of
