==Description==
In [http://en.wikipedia.org/wiki/Graph_theory graph theory], a biconnected component (or 2-connected component) is a maximal [http://en.wikipedia.org/wiki/Biconnected_graph biconnected subgraph]. Any connected graph decomposes into a tree of biconnected components called the block tree of the graph. The blocks are attached to each other at shared vertices called cut vertices or '''articulation points'''. Specifically, a cut vertex is any vertex that when removed increases the number of [http://en.wikipedia.org/wiki/Connected_component_(graph_theory) connected components].
