Probability density distributions of the clustering coefficient and average path length for WHPN and CASN. The blue and the red lines are for WHPN and CASN, respectively. (A) The decline for CASN is gentler than for WHPN. The x axis is the clustering coefficient with a range of 0 to 1. The probability density of the clustering coefficient is on the y axis. (B) Average path length is shown on the x axis and the probability density of average path length is on the y axis.
