Recently, I try to propose a new model for the visualization of PPI networks. The main problem of the model is how to collect subgraphs and how to visualize. There are over 165000 interactions meaning edges and over 6000 nodes. I do not want to code existing algorithms since then the production of subgraphs are done with C++ using OGDF. Interestingly, one of the subgraphs has the property of very high disconnectivity. Here are my first snapshots using Circular and Symmetric layouts in GDE graph editor.
