Graph

A graph is made up of multiple vertex and [[edges]] which connect them together.

A graph can be thought of as a network, a way to express the relationships between pairs of items. 1

Formally, a graph consists of two finite sets, \(V\) and \(E\), representing vertices and edges. The elements of \(E\) are unordered pairs of vertices.

For example: $$ V = {a, b, c, d, e, f} $$ $$ E = {(a, d), (a, e), (b, c)} $$
