A mathematical object that comprises

vertices interconnected with edges,

defined as an ordered pair of sets

\begin{equation*} G = (V, E), \end{equation*}

where	\(V\)	denotes the set of vertices and
	\(E\)	denotes the set of edges,

with \(E\) different per its type:

• undirected graph (the default)
• directed graph
• weighted graph.
