Fig. 4

Network analysis and visualization. a This figure represents specific degree measure of every node such as the nodes with yellow color are labeled with 1 which indicates nodes with 1 degree, the nodes with green color have 2 degree, red have 3, blue have 4, pink have 5, white have 6 and so on. b This figure represents 210 strong components. Digits labeled on the nodes (circles) show the component number. c This figure represents 1 weak component in yellow color. d This figure represents 6 cores in the network, yellow colored nodes belong from core 1, green from core 2, red from core 3, blue from core 4, pink from 5 and white colored nodes represent core 6
