Webbipartite (2,2)-Laman graphs — a certain family of graphs that contains all maximal bipartite planar graphs. 1. Introduction Wagner’s celebrated theorem [5], [2, Theorem 4.4.6] provides a characterization of planar graphs in terms of minors: a graph Gis planar if and only if it contains neither K5 nor K3,3 as a minor.
