What is a figure legend?

A figure legend is a brief description or explanation of a figure (such as a graph, chart, diagram, photograph, or illustration) that is included in a document or publication. The purpose of a figure legend is to provide important information about the figure that is not readily apparent, such as the significance of the data presented, the methods used to create the figure, or any relevant details that provide context for the figure.

Figure legends are typically placed below the figure and are usually written in a concise and clear manner. They should be descriptive, informative, and complete, but also succinct and to the point. Figure legends are important for helping readers understand and interpret the visual information presented in the figure, and they are essential for providing proper credit to the source of the figure.
