What role do images and diagrams play in technical writing?

Images and diagrams play a critical role in technical writing by visually representing information and clarifying complex concepts. They enhance understanding by providing a graphic representation of data, processes, or systems that may be difficult to convey through text alone. Visual aids can simplify complex information, illustrate relationships, and highlight key points, making it easier for readers to grasp the material quickly.

For instance, a flowchart can outline a process in a clear and concise manner, allowing readers to see the steps involved at a glance. Similarly, diagrams can depict structures or systems, helping to make the information more relatable and accessible. This use of visual elements not only aids in comprehension but can also improve retention of information, as people often remember visuals better than text.

Other choices suggest that images might serve a lesser purpose, such as being merely decorative or serving to replace written explanations completely, neither of which accurately captures their intended function in effective technical communication.
