When you were young, the grown-ups used to catch you doodling little circles and lines on the back of your exercise books or paper napkins, instead of paying attention to what they said. They didn't realize that you need to sketch things out, how they relate to other things, in order to get them into your head and other people's heads.
Much later, you learnt the grown-up names for these sketches - mind maps, concept maps, semantic networks, org charts, flowcharts, social networks, genomic hierarchies, E-R diagrams...
