What is the term used for a visual representation that illustrates an accident or crime?

The term "Diagram illustration" refers to a visual representation that is used to depict the details of an accident or crime. It typically includes important elements such as the positions of vehicles, the location of evidence, and any other relevant features that help in understanding the scene.

In a law enforcement context, diagrams or sketches can be critical in providing clarity and detail about the incident. They can serve as a visual aid during investigations and can be used in court to assist in conveying the sequence of events or the overall layout of the scene.

While photographs capture specific moments in time and are essential for documenting evidence, a diagram serves a different purpose by offering a more abstract representation that can help to reconstruct events in a way that is easily understandable to others. This reinforces why "Diagram illustration" is the appropriate term for this type of visual representation.
