Graph Theory Questions Medium
A planar graph is a type of graph that can be drawn on a plane without any of its edges crossing each other. In other words, it is a graph that can be represented in such a way that its edges do not intersect. Planar graphs are often visualized as diagrams or drawings where the vertices are represented by points and the edges are represented by curves or lines connecting these points. The concept of planarity is important in graph theory as it has various applications in fields such as computer science, network design, and circuit theory.
