What are explanatory visuals used for in technical writing?

Explanatory visuals are critical in technical writing because they serve to clarify complex information and enhance the reader's understanding of the content. These visuals, which can include charts, graphs, diagrams, and illustrations, break down intricate concepts into more digestible forms. When technical information is accompanied by relevant visuals, it helps readers grasp the material more easily, allowing for better retention and comprehension.

The main purpose of using explanatory visuals is to reduce cognitive load and make the technical content more accessible. For instance, a diagram demonstrating a process can effectively illustrate steps that might be cumbersome to explain purely through text. This use of visuals supports readers in identifying relationships, trends, and patterns that might otherwise go unnoticed in written descriptions alone.

In contrast, options that focus solely on decoration, emotional appeal, or personal anecdotes divert from the primary purpose of explanatory visuals. These alternative approaches do not enhance the clarity or understanding of technical content, which is the fundamental goal in effective technical writing.
