Graph
In computer science, agraphis an abstract data type that is meant to implement the undirected graph and directed graph concepts from mathematics, specifically the field of graph theory
A graph data structure consists of a finite (and possibly mutable) set of vertices or nodes or points, together with a set of unordered pairs of these vertices for an undirected graph or a set of ordered pairs for a directed graph. These pairs are known as edges, arcs, or lines for an undirected graph and as arrows, directed edges, directed arcs, or directed lines for a directed graph. The vertices may be part of t
