Planar Embedding

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. Equivalently, a planar embedding is an embedding of a graph drawn in the plane such that edges intersect only at their endpoints.

A planar straight line embedding of a planar graph can be constructed in the Wolfram Language using the "PlanarEmbedding" option to GraphLayout or using PlanarGraph[g].

Precomputed planar embeddings of some graphs are available in the Wolfram Language as GraphData[g, "Graph", "Planar"].
