SPQR-tree

From Wikipedia, the free encyclopedia

The SPQR-tree is a tree data structure that represents the decomposition of a biconnected graph with respect to its triconnected components. It was introduced by Di Battista and Tamassia [1] [2]. Its main application is planarity testing and graph drawing.
