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 can be drawn in such a way that no edges cross each other.

What Are Planar Graphs? | Baeldung on Computer Science
Mar 18, 2024 · A planar graph is a graph that can be drawn on a plane such that its edges intersect only at their end nodes. A plane graph is a graph whose edges don’t intersect. So, we call a graph planar if we can draw it as a plane graph.
4.2: Planar Graphs - Mathematics LibreTexts
When a connected graph can be drawn without any edges crossing, it is called planar. When a planar graph is drawn in this way, it divides the plane into regions called faces. Draw, if possible, two different planar graphs with the same number of vertices, edges, and faces.

What are planar graphs? How can we draw them in the plane? In today's graph theory lesson we'll be defining planar graphs, plane graphs, regions of plane gra...
15.1: Planar Graphs - Mathematics LibreTexts
A graph is planar if it can be drawn in the plane (\(\mathbb{R}^2\)) so edges that do not share an endvertex have no points in common, and edges that do share an endvertex have no other points in common. Such a drawing is called a planar embedding of the graph.
A graph is called planar if it can be drawn in the plane (R2) with vertex v drawn as a point f(v) 2R 2 , and edge (u;v) drawn as a continuous curve between f(u) and f(v), such that no two edges intersect (except possibly at the end-points).
Planar Graph -- from Wolfram MathWorld
A graph is planar if it can be drawn in a plane without graph edges crossing (i.e., it has graph crossing number 0). The number of planar graphs with n=1, 2, ... nodes are 1, 2, 4, 11, 33, 142, 822, 6966, 79853, ...
