Which best describes a 'diagram'?

A diagram is accurately described as a simplified drawing that visually represents the appearance or workings of something. Diagrams serve as effective tools for conveying complex information in a clear and concise manner. They can illustrate relationships, processes, or structures, making them particularly useful in educational contexts, technical fields, and various forms of communication. By simplifying and organizing information graphically, diagrams enhance understanding and retention, allowing viewers to grasp concepts quickly without needing lengthy explanations.

This definition distinguishes diagrams from other forms of expression, such as narratives or detailed analyses, which focus more on text and storytelling instead of visual simplification.
