WebNov 18, 2024 · The Basics of Graph Theory. 2.1. The Definition of a Graph. A graph is a structure that comprises a set of vertices and a set of edges. So in order to have a graph we need to define the elements of two sets: vertices and edges. The vertices are the elementary units that a graph must have, in order for it to exist.
