The authors investigated whether the type of data display (bar chart, pie chart, or table) or adding a gratuitous third dimension (shading to give the illusion of depth) affects the accuracy of answers of questions about the data. They conducted a randomized experiment with 897 members of the American Life Panel, a nationally representative US web survey panel. They found that displaying data in a table lead to more accurate answers than the choice of bar charts or pie charts. Adding a gratuitous third dimension had no effect on the accuracy of the answers for the bar chart and a small but significant negative effect for the pie chart. Viewing the graph/table for less than 8 seconds resulted in less accurate answers. Older age was associated with increased average viewing time (1.2 seconds per 10 years increase in age) but did not affect the accuracy of the answers. Greater numeracy was associated with more accurate answers.

Although it is apparent that people are able to make inferences from graphs, it is presently unclear how they do so, even from simple graphs. Current theories of graph comprehension are largely silent about the processes by which such inferences are made (e.g., Freedman and Shah, 2002; Pinker, 1990). The authors propose that people use spatial reasoning, in the form of spatial transformations (Trafton, Trickett, and Mintz, in press), to answer inferential questions. Spatial transformations are cognitive operations that a person performs on internal or external visualizations, such as graphs. They occur when people must mentally create or delete something (e.g., a line) on the image to facilitate problem solving, and may be related to hypothetical drawing (Shimojima and Fukaya, 2003). This paper investigates the use of spatial transformations when people need to make inferences from graphs.

"Human processing of graphical information is a topic which has wide-reaching implications for decision-making in a variety of contexts. A deeper understanding of the processes of graphical perception can lead to the development of design guidelines which can enhance performance in graphical perception tasks. This study evaluates the data-ink ratio guideline, which recommends the removal of non-data graph elements, resulting in minimalist graph designs. In an experiment, participants answered graph comprehension questions using bar graphs and boxplots with varying data-ink ratios. Participants answered questions with similar levels of accuracy and mental effort. Some participants drew on graphs, reducing the data-ink ratio of high and medium data-ink stimuli. Additionally, expert interviews were conducted regarding graph use, graph creation, and opinions about the data-ink concept and example graphs. Interviewees had a variety of opinions and preferences with regard to graph design, many of which were dependent upon the specific circumstances of presentation. Most interviewees did not think that high data-ink graph designs were superior. These results suggest that data-ink maximization does not improve performance in graph comprehensions tasks, and that arguments regarding the data-ink ratio deal with the subjective issue of graph aesthetics"--Abstract.

This study examined how graph readers extract specific information, integrate information, and make inferences from choropleth graphs. The authors present a hierarchical framework of graph comprehension that suggests how graph readers extract different types of information. The framework suggests that the cognitive operations required to extract different types of information build in a hierarchical fashion as the complexity of the type of extraction increases. Empirical data gathered in their laboratory is reviewed in support of the hierarchical framework, and implications of the work are discussed.

Task analytic theories of graph comprehension account for the perceptual and conceptual processes required to extract specific information from graphs. Comparatively, the processes underlying information integration have received less attention. We propose a new framework for information integration that highlights visual integration and cognitive integration. During visual integration, pattern recognition processes are used to form visual clusters of information; these visual clusters are then used to reason about the graph during cognitive integration. In three experiments the processes required to extract specific information and to integrate information were examined by collecting verbal protocol and eye movement data. Results supported the task analytic theories for specific information extraction and the processes of visual and cognitive integration for integrative questions. Further, the integrative processes scaled up as graph complexity increased, highlighting the importance of these processes for integration in more complex graphs. Finally, based on this framework, design principles to improve both visual and cognitive integration are described.
