This project is designed as an add-on for networkx, a graph library for Python. It accepts a variety of different spatial formats to generate directional graphs and provides simple modules to correct flow errors, find specific nodes by attribute, and run a depth first search (trace) with stopping points.
PySAL is an open source library of spatial analysis functions written in Python intended to support the development of high level applications.
