A mind map is a diagram used to visually outline information. A mind map is often created around a single word or text, placed in the center, to which associated ideas, words and concepts are added. Major categories radiate from a central node, and lesser categories are sub-branches of larger branches. Categories can represent words, ideas, tasks, or other items related to a central key word or idea.
Mindmaps can be drawn by hand, either as “rough notes” during a lecture or meeting, for example, or as higher quality pictures when more time is available. An example of a rough mind map is illustrated.
Other terms for this diagramming style are: “spider diagrams,” “spidergrams,” “spidergraphs,” “webs”, “mind webs”, or “webbing”, and “idea sun bursting”. (A “spider diagram” used in mathematics and logic is different.)
