What Are Planar Graphs? | Baeldung on Computer Science
2024年3月18日 — 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.
Planar Embedding -- from Wolfram MathWorld
2024年11月21日 — A planar embedding, also called a "plane graph" (Harary 1994, p. 103; Harborth and Möller 1994), "planar drawing," or "plane drawing," of a planar graph is an embedding in which no two edges intersect (or overlap) and no two vertices coincide.
In a plane graph, every cycle is the symmetric difference of the bound-aries of some faces. For every face of a given plane graph G, there is a drawing of G for which the face is exterior. Let G be a plane graph.

Planar Graphs and Plane Graphs If a graph Gis embeddable on the plane (or the sphere), Gis called a planar graph; otherwise Gis called a non-planar graph. If Gis a planar graph,...
5.3 Planar Graphs and Euler’s Formula Among the most ubiquitous graphs that arise in applications are those that can be drawn in the plane without edges crossing.
1 Plane andPlanar Graphs Definition 1 A graph G(V,E) is called plane if • V is a set of points in the plane; • E is a set of curves in the plane such that 1. every curve contains at most two vertices and these vertices are the ends of the curve; 2. the intersection of every two curves is either empty, or one, or two vertices of the graph ...
