WebOct 20, 2024 · A directed graph is a data structure that stores data in vertices or nodes and these nodes or vertices are connected and also directed by edges (one vertex is directed towards another vertex through an edge) that may have some weight. Directed graph is also called a digraph or directed network. WebMay 26, 2024 · Directed graphs have edges that point from one vertex to another. One can only go one direction on an edge. Non-directed / bidirectional graphs have edges where you can go back and forth between vertices. Cyclic graphs are graphs with cycles. Basically, there is at least one path in the graph where a vertex can come back to itself.

WebDirected Graph: The directed graph is also known as the digraph, which is a collection of set of vertices edges. Here the edges will be directed edges, and each edge will be connected with order pair of vertices. In a graph, the directed edge or arrow points from the first/ original vertex to the second/ destination vertex in the pair.
