math/py-grandalf 0.8_1 MidnightBSD

Grandalf is a python package made for experimentations with graphs drawing algorithms. It is written in pure python, and currently implements two layouts: the Sugiyama hierarchical layout and the force-driven or energy minimization approach. While not as fast or featured as graphviz or other libraries like OGDF (C++), it provides a way to walk and draw graphs no larger than thousands of nodes, while keeping the source code simple enough to make it possible to easily tweak and hack any part of it for experimental purpose.
