Abstract: Visualizations act as cognitive aids by making reasoning tractable. To choose an appropriate visualization, designers need to know about the cognitive advantages and disadvantages of different visualization techniques. While considerable research has focused on low-level perceptual issues related to visual encodings and judgments, less research has focused on the cognitive operations that are supported by visualization techniques. We conducted a pilot study using mixed methods to uncover properties of some common visualization tech- niques that allow propositional statements to be directly observed rather than indirectly inferred. We describe the results of our study and discuss potential benefits of this line of research to visualization designers and researchers.
