Figure 8.
The scatter plot has Betweenness k on the horizontal axis and P of Betweenness greater than or equal to k on the vertical axis. The horizontal scale ranges from one to above 1000. The vertical scale ranges from 0.01 to 1.00. Data points start above 0.50 at low betweenness values. The points decline steadily as betweenness increases. The decrease becomes steeper in the higher range. The largest betweenness values correspond to the lowest probabilities, falling to below 0.01 near the far right.Betweenness distribution (log-log)
