Adjacency matrices show the number of direct links between vertices in a network. The topmost row and the leftmost column consist of the vertex labels, and the number in the corresponding cell indicates the number of direct links between the vertices. If A is directly linked to B then B is directly linked to A, so the adjacency matrix is symmetrical about the diagonal from upper left to bottom right.
