From time to time in popular media, someone fills a whiteboard or bulletin board with many small notes, documents and pictures. Often, red lines (pieces of string) are pricked on there as well, connecting items to indicate probable relationships. The goal of these is usually to aid a person in their investigation of something (a conspiracy, plot, plan, etc.)
The only name I have so far found that describes these is the rather informal 'conspiracy wall'.
Because I actually like to order my thoughts and ideas in a very similar way to this (not usually related to conspiracies but rather in the process of writing a story/worldbuilding), I would like to inquire if this technique has a more proper or formal name (that preferably does not include the word 'conspiracy' ^_^).
