Network models. (A) An Erdos–Rényi random network. (B) A Watts-Strogatz network. (C) Barabási–Albert (BA) scale-free network. Graphs were visualized using R. Code example: g1 = sample_smallworld (1, size = 500, nei = 4, p = 0.03). Plot (g1, layout = layout.fruchterman.reingold, vertex.label = NA, edge.arrow.size = 0.02, vertex.size = 0.5, xlab = “Random Network: G(N,p) model”).
