Figure 2.

Drosophila PPI module networks: the relationship between fundamental network concepts NetworkConcept(A - I) (y-axis) and their approximate CF-based analogs NetworkConcept_CF,app (x-axis). This figure demonstrates Observation 2. A) Density versus Density_CF,app; B) Centralization versus Centralization_CF,app; C) Heterogeneity versus Heterogeneity_CF,app; D) Intramodular clustering coefficients ClusterCoef_i versus ClusterCoef_CF,app. In Figures A), B) and C), each dot corresponds to a module since these network concepts summarize an entire network module. In Figure D), each dot corresponds to a node since these network concepts are node specific. A reference line with intercept 0 and slope 1 has been added to each plot.
