Planar Graphs Graph Coloring

Planar Graphs Graph Coloring. Chapter 9.7-9.8. Introduction. Consider the complete bipartite graph K3,3 . Can K3 ,3 be drawn in the plane so that no two of its edges cross? In this section we will study the question of whether a graph can be drawn in the plane without edges crossing .
