A diagram could be a model. * A model is a representation of something in nature or a
prototype of an idea or solution important to engineering.
Models often represent phenomenon that are difficult to observe

or drawing. In fact, equations, diagrams and drawings are often
used to model very complex ideas in a simple way.
