Planar graph - Wikipedia
In graph theory, a planar graph is a graph that can be embedded in the plane, i.e., it can be drawn on the plane in such a way that its edges intersect only at their endpoints. In other words, it …

A planar graph is a graph that can be embedded in the plane, meaning it can be drawn on a flat surface such that no two edges cross each other.
Planar Graphs - Simon Fraser University
There might be another way to draw it so it is planar. When we draw a planar graph, it divides the plane up into regions. For example, this graph divides the plane into four regions: three inside …
