How do you display adjacency matrix?

An adjacency matrix is displayed as a square grid where both rows and columns represent the nodes (or vertices) of a graph. Each cell in the matrix indicates the presence or absence of an edge between the corresponding nodes, typically using a 1 for an edge and a 0 for no edge in an unweighted graph. For directed graphs, the matrix is not necessarily symmetric, while in undirected graphs, it is symmetric. To create a clear visual representation, it's common to label the rows and columns with the node identifiers.
