2 Chris Bennett & Jody Ryall & Leo Spalteholz & Amy Gooch / Aesthetics of Graph Visualization
Figure 1: Conceptual model of the factors involved in the interpretation of graph visualizations.
- 2. Perception & Cognition
Node-link diagrams are simply a collection of points and
- lines. Involuntary and voluntary processes drive the viewer’s
ability to extract shapes and draw meaning from such dia-
- grams. Norman [Nor04] groups these processes into three
levels: visceral, behavioural, and reflective. The visceral level includes the basic perceptual tasks of distinguishing
- bjects and forming our true first impressions. The be-
havioural level builds upon output from the perceptual level, and focuses on issues such as readability and usability. The reflective level refers to the higher levels of emotion and cog-
- nition. Originally applied to the design of everyday things,
this model can help us to understand how we process and evaluate graph visualizations. 2.1. Visceral Level thorough treatment of Gestalt principles as they apply to graph drawing, assigning the principles to perceptual group- ing and perceptual segregation categories. Perceptual grouping principles include:
- Good figure – refers to the simplicity and stability of a
figure [WS06];
- Similarity – elements with common features, such as
colour or shape, appear to be grouped [WS06];
- Continuation – colinear or near colinear elements tend to
be grouped [DS06];
- Proximity – elements that are closer are more likely to be
grouped [DS06,WS06];
- Connectedness – physically connected elements are usu-
ally grouped [WS06]; and
- Familiarity – elements that seem familiar or meaningful
are more likely to be grouped [WS06]

concept
- Visual change = prevention of sudden rush
- Clock = Overall, history and the time now
- History = preventing errors
- Weather forecast = not isolated
- Compare parameters = deeper understanding of the quality
- Device = Communication, Engagement, get physical
- Indicating = Locate the problem
