Graph theory root tree
http://duoduokou.com/python/50816558465554824191.html WebTree. In graph theory, a tree is an undirected, connected and acyclic graph. In other words, a connected graph that does not contain even a single cycle is called a tree. A tree represents hierarchical structure in a graphical form. The elements of trees are called their nodes and the edges of the tree are called branches.
