Which of the following is characteristic of annotated diagrams?

Annotated diagrams are characterized by the inclusion of text annotations alongside graphics. This combination provides a clearer understanding of the visual elements by offering explanations, labels, or additional context that enhances the viewer's comprehension of the diagram's key points. The text annotations serve to guide the audience through the visual information, making complex data or concepts more accessible and easier to interpret.

In contrast, other options do not accurately reflect the nature of annotated diagrams. Focusing exclusively on aesthetic visuals does not capture the informative aspect that annotations provide. Furthermore, while some annotated diagrams may appear in technical documentation, they are not limited to this context; they can be utilized in various fields such as education, marketing, and more. Lastly, representing only one concept at a time is not a defining feature of annotated diagrams; they can display multiple interconnected ideas within a single diagram while still effectively utilizing annotations to clarify these relationships.
