This is a Flow Map. Flow Maps are a unique amalgamation of flow charts and maps. Flow Maps show the movement of data from one location to another. According to the site that this map was found on, flow maps are often drawn by hand because there are few algorithms available to generate this type of map on a computer. (However, it should be noted that this site is dated in 2005, so this information could be outdated.) I liked the unique eyecatching look of this map. This map originally appeared in the UK Interdependence Report.
