broader: cartography
definition: Flow maps depict the movement of phenomena between geographic locations, typically using lines of varying widths to depict quantitative data, although different color hues, in the case of qualitative data, may also be used. In the older literature, flow maps are also referred to as dynamic maps. [Source: Encyclopedia of Geography; Flow Maps]
