Large scale network properties revealed by shape. A) Undirected Erdos-Renyi graph with 10K nodes and 60K edges; B) undirected Erdos-Renyi graph with 10K nodes and 10K edges; C) undirected Barabasi-Albert scale-free graph with 2K nodes, six edges added each time step, generated using psumtree algorithm. All were generated using the R igraph v0.6 package [35] and laid out using BioFabric default layout technique. These networks are not shown to the same scale. The shapes of the lower and upper boundaries, and large-scale edge patterns show basic network properties; see text for discussion.
