Legends, also called map a “key,” define the meaning of symbols and styles used on a map. The choice to include a legend depends on your map’s purpose and your audience. Maps do not need legends if the symbology is so common or simple as to be easily understood by the reader. However, it must be clear what the symbols represent.
Legends are created by laying out symbols, styles and text. When creating a legend, use guidelines to keep your layout tidy.
