In computer science, a **graph** is 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
|
||
the graph structure, or may be external entities
|
||
represented by integer indices or references.
