Ideally, a well-designed structure is displayed which an individual can use to organize incoming information. Rather than having to take in many separate pieces of information and organize them individually, the information is already arranged coherently. This facilitates the task of remembering and comprehension.

Simulations and visualizations are, for a variety of reasons, effective at engaging the user. I find the colors, shapes, and patterns pull my attention in a way that text cannot. Another property which makes these tools engaging is their interactive capacities, as can be seen with this stock and flow diagram. In such cases, the user has the ability to change the values of important variables. The user is positioned as an active component in the production of whatever result the tool generates.
