What does a "legend" provide in display design?

A legend in display design is essential for enhancing user comprehension by providing explanations of symbols, colors, or terms utilized within the display. This helps users interpret the information accurately and understand the relationships between different elements more effectively. For instance, a legend might clarify what specific colors represent in a graph or what various symbols mean in a diagram, ultimately guiding the user to make informed decisions based on the displayed data.

This function is crucial in any visual communication tool, as it acts as a reference point that demystifies the content being presented. By doing so, a legend ensures that users are not left guessing about the meanings behind visual cues, which can lead to misinterpretation or confusion. While other aspects of display design may influence aesthetics or operational definitions, the primary role of a legend centers on clarity and user-friendliness in conveying complex information.
