In the special case of a finite simple graph, the adjacency matrix is a (0,1)-matrix with zeros on its diagonal. In graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph.The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph.. name = vertex. The way NumPy implements this is with a dense matrix where each value is a Byte. Also, keep an array to keep track of the visited vertices i.e. Here’s my code: In fact, in Python you must go out of your way to even create a matrix structure like the one in Figure 3 . One way to represent a graph as a matrix is to place the weight of each edge in one element of the matrix (or a zero if there is no edge). It is possible to represent a graph in a couple of ways: with an adjacency matrix (that can be implemented as a 2-dimensional list and that is useful for dense graphs) or with an adjacency list (useful for sparse graphs).

As @misha mentioned, this list is not enough to represent the interconnectedness of nodes, because edges between nodes may have a weight of 0, which would be indistinguishable from an edge not existing at all, so both the edges and the vertices matrices are necessary. Graphs are collections of things and the relationships or connections between them. Notes. In this post, we discuss how to store them inside the computer.
