Figure 3

Ratio of nodes overlapping in the top 10% (K nodes) of spreader assignment by 10 centrality metrics (degree, closeness, betweenness, HITS, PageRank, Hirsch index, LeaderRank, -shell, local centrality, and eigenvector centrality) in an Erdos-Renyi (Rand) random network, mesh network, small-world (SW), and scale-free (SF) network. The blue colour intensity of a cell corresponds to the strength of correlation found in the symmetric cell, that is, . A stronger blue intensity denotes a stronger correlation.
