Connector Map

Connector Maps feature a set of straight and/or curved lines connecting points on a geographical map.
Lines can vary in width, color, and style. Unlike in Flow Map, they have no direction and only display a connection between two points. Points on both sides of each line are depicted with markers that also can vary in size, color, and style.
A typical use of Connector Maps visualizations is to outline territories, routes, rivers, and connections between geographic locations.
