Mind mapping is a method for drawing one or more diagrams to visually organize knowledge and information, for instance about a trend or a megatrend. A mind map is often created around a single concept to which associated representations of ideas such as images, words and parts of words are added. Major ideas are connected directly to the central concept, and other ideas branch out from those.
