AddVertices

AddVertices[g, n]
adds n disconnected vertices to graph g.

AddVertices[g, vList]
adds vertices in vList to

. vList contains embedding and graphics information and can have the form

or ${{x_1,y_1},{x_2,y_2} …}$ or the form ${{{x_1,y_1},g_1},{{x_2,y_2},g_2},…}$ , where

, ${x_1,y_1}$ , and ${x_2,y_2}$ are point coordinates and

and

are graphics information associated with vertices.

To use AddVertices, you first need to load the Combinatorica Package using Needs["Combinatorica`"].
