A visualization of an idea, often created on paper or through software, in two or three dimensions, is called which term?

• A. Mock-ups
• B. Physical modelling
• C. Graphical models
• D. Instrumented models

Answer: (C)

Visualizing an idea in two or three dimensions on paper or with software is a graphical model. This focuses on a visual depiction that communicates form, structure, and relationships without being a physical replica or a live, tested object. Graphical models include sketches, CAD drawings, and digital renders—any 2D or 3D depiction that conveys the concept. A mock-up is typically a more tangible or near-final representation for testing look and feel, a physical model is an actual tangible replica, and an instrumented model includes sensors for data collection. The description given fits best with graphical models because it centers on the visual depiction created in paper or software.
