Fig. 1From: Comprehensive host-pathogen protein-protein interaction network analysisBipartite graph and its projection. Left graph shows a bipartite graph with 4 top nodes and 6 bottom nodes. Right graph illustrates the projection of the bipartite graph. Each top node in bipartite graph makes a clique in projection graph. Top nodes of the bipartite graph are colored by different colors to distinguish the related cliquesBack to article page
