Centrality-based visual analysis: focal node is in purple color in all networks, size correlates with centrality measures, whereas colors represent the degrees of the nodes in each network. a The one having purple color with the biggest size are the focal node having the highest degree in a network. b A visual display of the ranking (size) of the nodes with the highest betweenness centrality and partitioned (colored) on the basis of degree. c The ranking (size) of nodes with high closeness centrality. d The ranking (size) of the nodes with high eigenvector centrality
