I'm trying to find the faces of a planar graph in python. I know such a function exists in IGraphM, the Mathematica interface to igraph, but I'm wondering if that was implemented only in that interface or the python igraph also has something similar.
If not, then please feel free to give me ideas for how to solve the problem.
Planar graph functionality only exists in IGraph/M, not in the other interfaces of igraph. This is because IGraph/M uses parts of the LEMON graph library for this functionality, as well as code that's specifically written for IGraph/M.
