graph theory, topology: Let `G->S` is an imbedding. The regions are the components of the complement S-G. If a connected graph is imbedded in a sphere, then the complement of its image is a family of regions. The regions are sometimes like the faces of polygon. The on-sided region is called monogon, the two sided region is called digon.
