Clustered network shown in BioFabric. This is a BioFabric version of the network presented in Figure 4 of . The main image shows the whole network, while the inset shows a magnified version of Cluster 1. Note how the ability to group edges horizontally allows inter- and intra-cluster edges to be segregated for clarity. As the inset shows, the nodes in Cluster 1 that are the targets of the edges coming from Cluster 0 can be easily discerned.
