DualPlanarGraph
gives the dual of the planar graph g.
Details and Options

- DualPlanarGraph is also known as geometric dual graph and combinatorial dual graph.
- DualPlanarGraph is typically used to associate dual structures such as flow and cellular networks, or Voronoi and Delaunay diagrams.
- DualPlanarGraph[g] gives a graph that has a vertex for each face of g and an edge for each pair of faces separated from each other by an edge.
- DualPlanarGraph takes the same options as Graph.
