Labyrinth is a lightweight mind-mapping tool, written in Python using Gtk and Cairo to do the drawing. It is intended to be as light and intuitive as possible, but still provide a wide range of powerful features.
A mind-map is a diagram used to represent words, ideas, tasks or other items linked to and arranged radially around a central key word or idea. It is used to generate, visualise, structure and classify ideas, and as an aid in study, organisation, problem solving, and decision making. (From wikipedia)
