What type of evidence are charts, maps, or models?

Charts, maps, and models fall under the category of demonstrative evidence because they are visual representations used to illustrate or clarify information relevant to a case or situation. Demonstrative evidence is designed to make abstract or complex ideas more tangible and understandable, facilitating effective communication of concepts that might otherwise be difficult to convey through words alone.

In legal contexts, demonstrative evidence can signify the layout of a crime scene, illustrate the trajectory of a projectile, or provide a visual summary of data pertinent to a case, enhancing the jury's or viewers' understanding of the subject matter. This type of evidence helps to visualize relationships and contextualize the facts being presented, which is essential for effective storytelling in legal arguments.
