Which visual form shows relationships or explains a process?

• A. Captions below illustrations
• B. Charts or tables
• C. Diagrams
• D. Graphs

Answer: (C)

Diagrams are the best fit when you want a visual that shows how parts connect or how a series of steps leads from start to finish. They map relationships, sequences, and structures in a clear, spatial way that helps you see how elements interact or how a process unfolds. Think of a flowchart that lays out steps in a procedure, a circuit diagram showing how components connect, or a map of a system with arrows indicating how information or energy moves. These kinds of visuals organize the relationships and the progression of steps, making the overall picture easier to grasp. Captions add text to an image but don’t themselves illustrate how things relate or how a process operates. Charts or tables present data and quantities, which is great for comparisons or trends, but they don’t typically convey the mechanical or logical connections of a system. Graphs show how a value changes over time or across categories, which is about measurement, not the full web of relationships or the step-by-step flow.
