libtopology is a cross-platform C++ library providing extensions to the libcola and libavoid libraries to support topology-preserving layout.

libtopology is part of the Adaptagrams project. There are no official releases yet, though the code is stable and available from the Adaptagrams GitHub repository.

The API is documented using Doxygen. The documentation you are currently reading can be obtained by running doxygen in the cola directory.

libcola is written and maintained by Michael Wybrow and Tim Dwyer, members of Immersive Analytics Lab at Monash University, Australia.

The algorithms used for Topology Preservation are described in the following papers. If you use libtopology, please cite the relevant paper.
