Visual references are images or illustrations used to convey ideas, concepts, or information. They help enhance understanding by providing a clear representation of the subject matter. For example, in design, a visual reference can be a photograph or a sketch that guides the creation of a new product or artwork. In education, visual references can include charts, graphs, and diagrams that simplify complex information. They serve as tools to aid learning and retention, making it easier for students to grasp topics like mathematics or science. Overall, visual references play a crucial role in communication across various fields.
