What is not typically included in a documented diagram?

A documented diagram in the context of evidence collection is a critical tool used to visually represent the scene and the surrounding area related to an investigation. This diagram typically includes essential information such as the case number, date, and location to provide context and reference for the investigation.

Artistic impressions, however, are not a standard component of these diagrams. While the purpose of the diagram is to accurately portray the scene for legal and analytical purposes, artistic interpretations can introduce subjectivity and personal style, potentially leading to misrepresentation of the facts. The focus is on precision and clarity, ensuring that the diagram serves as a reliable reference that can be understood by law enforcement, forensic experts, and the courts. Thus, including artistic elements undermines the objective nature of the documentation.
