# (Network|Graph) - Directed Graph (or digraph)

A directed graph (or digraph) is a graph, where the edges have a direction associated with them.

Directed edges are suitable for modeling asymmetric relations

A undirected graph is the inverse where the edges have no direction information and are therefore bi-directional
