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. WebReturns a directed representation of the graph. Returns: G DiGraph.
