A molecular graph is a collection of points representing the atoms in the molecule and set of lines representing the covalent bonds. These points are named vertices and the lines are named edges in graph theory language. In mathematical terms a graph is represented as G =(V,E) where V is the set of vertices and E is the set of edges.
