# Combinatorial maps

CombinatorialSpaces has incomplete, experimental support for several combinatorial structures used in topological graph theory, such as combinatorial maps and rotation systems. For an introduction to rotation systems and their implementation, see this blog post at the AlgebraicJulia blog.

CombinatorialSpaces.CombinatorialMapsModule

Combinatorial maps and related structures, as C-sets.

In topological graph theory and graph drawing, an embedded graph is a combinatorial structure representing a graph embedded in an (oriented) surface, up to equivalence under (orientation-preserving) homeomorphism. This module defines data structures for rotation systems, combinatorial maps, and other combinatorial objects describing embedded graphs.
