Example of simplifying a graph by collapsing a group of nodes with same interacting partners into a composite node, shown as a diamond.
Sample (subset of human protein interactions)
Node: 307, Edge 1063
Node: 25, Edge 62 (A composite is represented in diamond shape.)
Example of simplifying a graph by collapsing into a composite node and clique into a star-shaped subgraph.
