Figure 2.

Average clustering coefficient and Distance of the domain bigram network versus the simulated network. A. Average clustering coefficient across domain bigram networks are plotted in red polyline along x-axis labeled with organism abbreviations (in the same order as in Figure 1). For the bigram network of each organism, 1000 simulated random networks with the same degree distribution are generated, and the mean and standard deviation of average clustering coefficient of simulated networks are shown in the figure with blue polyline (mean) and light blue vertical lines (standard deviation). B. Average distances of domain bigram networks and those of simulated networks, plotted in a similar manner as in A.
