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.[1] Categories can represent words, ideas, tasks, or other items related to a central key word or idea.
Mind maps 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.
Mind maps are considered to be a type of spider diagram.[2] A similar concept in the 1970s was "idea sun bursting".[3]
