Planar Graphs and Graph Coloring

This document explores key graph theory concepts, beginning with planar graphs—highlighting their definition, importance, and applications—followed by graph colouring, covering techniques and practical uses. It delves into the interplay between planar graphs and colouring through constraints and the Four Colour Theorem. Emphasis is placed on collaborative learning and effective knowledge sharing to enhance team understanding. The conclusion summarises core ideas, outlines applications for...
