The above map is an example of a flow map. These maps are designed to show the path of entities across a surface and it intensity. The paths in this map are highly idealized meaning it only shows the direction of interaction and not the actual path. This type of flow map is called a desire line map. These maps usually illustrate social or economic exchange using connection points of origin and destination. The above example shows the imports and exports from and to both the U.S. and China. This map also uses proportional circles to display data about a cities import value.
