Directed Graphs

A directed graph (also known as a digraph) is a type of graph where each edge has an orientation, meaning that it has a direction. They are useful for representing relationships between objects in a variety of ways. For example, in computer networks, directed graphs are used to represent communication paths between computers or servers. In social networks, directed graphs are used to represent relationships between people, such as friendships or families. Furthermore, directed graphs can be used in finance or economics to represent financial relationships between companies or countries. They are also used in transportation, engineering, and other fields. Directed graphs are a powerful tool for visualising, analysing and understanding complex systems.
