In graph theory, graph coloring is a special case of graph labeling; it is an assignment of labels traditionally called "colors" to elements of a graph subject to certain constraints. In its simplest form, it is a way of coloring the vertices of a graph such that no two adjacent vertices are of the same color; this is called a vertex coloring. Similarly, an edge coloring assigns a color to each edge so tha… WebJul 13, 2012 · A map is a collection of points. And Graph Theory is the study of graphs. Also, a planar graph is a graph in which no edges overlap each other. The Four Color Theorem only applies explicitly to maps on flat, 2D surfaces, but as I'll be talking about, the theorem holds for the surfaces of many 3D shapes as well.
