A continuum looks similar to a timeline, however it is not serial. Instead, continua represent the range of possibilities represented by a concept. They are well suited for material that contains many gradations between two extremes. Figure 6 represents a sample continuum. They represent the logical evaluation of an argument, presenting support for drawing a particular conclusion.
More complex structures contain sequences of reasoning, with explanations.
Premises - Reasoning Chain 1. Complex Argumentation Structure Spider maps, and the similar fishbone maps, are well suited to diagramming a central concept surrounded by related information. This may consist of an object and its attributes, or a primary concept with arms and legs for each major supporting idea. A branch from each leg for details of each idea may be included. Another example consists of a central proposition with supporting material, quotes, data, and examples, each on their own leg.
