This is a simple class library for drawing trees in a reasonably pretty fashion. It provides only minimal default drawing capabilities, since the algorithm is meant to be used for implementing custom tree-based tools.
Directed graphs may also be drawn using this library, if cycles are removed before the nodes and arcs are passed to the algorithm.
Tree displays are used in many applications: directory browsers, hypertext systems, class browsers, and decision trees are a few possibilities.
See the separate manual and the directory utils/wxtree.
