Graphs are studied in graph theory, a part of discrete mathematics. A graph data structure consists of a finite set of two types of objects:
The formal, mathematical definition for a graph is just this: G = (V, E). This means a graph is an ordered pair of a finite set of vertices and a finite set of edges.
If all edges within a graph are bidirectional, the graph is undirected. A simple, undirected graph is shown as follows:

This graph consists of four nodes and four edges. The set of nodes and edges can be represented with a formula ...
