Planar Graphs

A planar graph is a type of graph where the points (called vertices) and connections between them (called edges) can be drawn on a flat surface without any lines crossing each other. This means you can visualize the connections in a way that keeps the edges separate. A common example is a map, where towns are points and roads are edges, arranged so the roads don’t intersect except at the towns. Planar graphs are important in fields like geography, network design, and computer science, providing a way to understand relationships in a clear and organized manner.
