What can a legend show on a map?
A legend shows the meaning of the symbols, colors, and styles used to represent geographic data on the map. Legends consist of examples of the symbols on the map with labels containing explanatory text. Legends have patches that match the map symbols, which are often points, straight lines, rectangles, or color ramps.
