what is a graph?
In mathematics, and more especially in graph theory, a graph is a structure amounting to a set of objects wherein a few pairs of the objects are in a few sense "related". The objects correspond to mathematical abstractions known as vertices and each of the related pairs of vertices is known as an edge.
