What is the purpose of diagrams in informational texts?

Diagrams in informational texts serve to clarify complex information by visually representing data, processes, or relationships. They enhance understanding by breaking down content into easily digestible parts, making it more accessible. Additionally, diagrams can illustrate comparisons, hierarchies, or timelines, providing readers with a quick reference that complements the written material. Overall, they contribute to better retention and comprehension of the text.
