WebFeb 1, 2024 · If the edges between the nodes are undirected, the graph is called an undirected graph. If an edge is directed from one vertex (node) to another, a graph is called a directed graph. An directed edge is called an arc. Though graphs may look very theoretical, many practical problems can be represented by graphs.
