What are Graphs?

• B. Captions for images.
• C. Charts that represent data, such as pie charts, bar graphs, line graphs.
• D. Maps showing terrain.

Answer: (C)

Graphs are visual representations of data that help you see patterns, comparisons, and changes at a glance. They turn numbers into pictures so you can quickly grasp how values relate to one another. Common examples include pie charts, which show parts of a whole; bar graphs, which compare different categories; and line graphs, which reveal trends over time. These are graphs because they organize data with visual elements like slices, bars, or lines to illustrate quantities, not just text or images. Sidebars with extra text provide supplemental information, captions describe a specific image, and maps show geography or terrain—each serves a different purpose, not the overall data visualization that graphs provide.
