The term "illustrative" refers to something that serves to explain or clarify a concept, idea, or process. It often involves the use of images, diagrams, or examples to make information more accessible and understandable. For instance, an illustrative diagram can help visualize complex data, making it easier for the audience to grasp the main points. In literature and education, illustrative examples are frequently used to support arguments or teachings. These examples provide context and help readers or students relate to the material, enhancing their comprehension and retention of the subject matter.
