A list that identifies patterns, symbols or colors used in a chart?

• A. Legend
• B. Key
• C. Scale
• D. Grid

Answer: (A)

The main idea is how a chart explains its visual cues. A legend is the part that lists the patterns, symbols, or colors and explains what each one represents, so you can map colors or shapes to the actual data categories. Without this guide, the chart’s visuals would be hard to interpret. The other terms refer to different functions: the scale shows measurement units on an axis, and the grid provides reference lines for aligning data. While a key can be used in some contexts, legend is the standard term for the component that clarifies what the visual cues mean.
