Vertex degree distributions of networkswith t ranging from 0.013 to 0.011 (panel A) and from 0.01 to 0.006 (panel B). Both axes are on logarithmic scale. Each point represents one vertex degree value. Points are only connected by lines if their degree values differ by 1. A Approximately linear curves for 0.013 ≥ t ≥ 0.011. B From 0.01 to 0.006, vertex degree distributions become increasingly bell-shaped.
