WebJun 27, 2024 · Directed graphs have edges that are directional and not necessarily reciprocal. If a vertex in a directed graph is connected to … WebWhen each connection in a graph has a direction, we call the graph a directed graph, or digraph, for short. The directed edges of a digraph are thus defined by ordered pairs of vertices (as opposed to unordered pairs of vertices in an undirected graph) and represented with arrows in visual representations of digraphs, as shown below.

WebDirected Graph: A graph in which edges represent direction is called a directed graph. In a directed graph, we use arrows instead of lines (edges). Direction denotes the way to reach from one node to another node. Note that in a directed graph, we can move either in one direction or in both directions.
