A diagram is a graphic representation of a structure, situation, or process.

Carpenter utilizes the diagram well in his E-literature. Every slide has a picture of a geographical map.

There is a strong focus on the location in this piece. Carpenter even named the work after it, The Cape. The cape is so important to the story that it becomes an active character. The diagrams bring attention to the role of the cape.

The diagram not only gives the viewer a better sense of where the characters are geographically, but it also adds information to the story. As I mentioned in an earlier post, Carpenter usually speaks with short, factual statements. The diagram complement his factual tone with their own factual information. The diagram to the left shows wave directions in Cape Cod.

Carpenter also places directional and other map symbols throughout the work.

Diagrams help authors to be more exact. By showing a picture and labeling the picture, authors can show viewers exactly what they wish to prove. Instead of having to describe it.
