Which data organization method uses colors to distinguish categories?

• A. Graph
• B. Color-code
• C. Timeline
• D. Histogram

Answer: (B)

Color-coding is the method that uses colors to separate different groups in data. By giving each category its own color, you can quickly scan a chart or map and see which items belong together, compare groups at a glance, and spot patterns more easily. For example, in a chart showing types of landforms, you might color mountains green, plains yellow, and deserts tan, so you can instantly tell how many of each category there are and where they appear. Other displays serve different purposes. A graph is mainly about showing relationships between numerical values, a timeline arranges events in chronological order, and a histogram shows how often numbers occur within ranges. Colors can appear in those displays, but the core idea described here is using colors to distinguish categories.
