spqrtree
========

A pure Python SPQR-tree implementation for biconnected graphs.

**spqrtree** decomposes a biconnected graph into its triconnected
components and organizes them as an SPQR-tree, a classical data
structure in graph theory used for planarity testing, graph drawing,
and network analysis.
