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 …

May 18, 2021 · While vertices and edges are the basic components of a graph, faces are not properties of the graph itself but rather characteristics of a particular embedding. By …

Chernoff faces, invented by applied mathematician, statistician, and physicist Herman Chernoff in 1973, display multivariate data in the shape of a human face. The individual parts, such as …

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 …

When a planar graph is drawn with no crossing edges, it divides the plane into a set of regions, called faces. Each face is bounded by a closed walk called the boundary of the face. By …

2) The face graph is a graph with a vertex corresponding to each region, where two vertices are connected by an edge if and only if the corresponding regions share a border.

Jan 13, 2025 · In this article we will deal with finding both inner and outer faces of a planar graph. We will assume that the graph is connected. In this section we present several facts about …

Jun 11, 2017 · Generally, a face is a component polygon, polyhedron, or polytope. A two-dimensional face thus has vertices and edges, and can be used to make cells. More formally, …
