Graph coloring

Graph coloring is a way of coloring the nodes (or points) in a graph. Each node can have one of a certain number of different colors, and the goal is to use as few colors as possible. For example, if you have a graph with 5 nodes, you may be able to color it using only 3 colors. The rules for coloring graphs say that no two adjacent nodes (nodes that are directly connected) can have the same color. That way all the nodes are different colors and it looks nice!
