Community detection partitions nodes into six highly-interconnected communities. Communities (shaded groups along the diagonal) and their respective sub-communities (smallest squares along the diagonal) are shown. Each row depicts all connections a node sends, while its corresponding column depicts all the connections it receives. Within sub-communities, nodes are in descending order of degree. The nodes making up each community and sub-community are presented in Table 3, organized in the same manner
