Data can be visually represented using visual channels like position, length or luminance. An existing ranking of these visual channels is based on how accurately participants could report the ratio between two depicted values. There is an assumption that this ranking should hold for different tasks and for different numbers of marks. However, there is surprisingly little existing work that tests this assumption, especially given that visually computing ratios is relatively unimportant in real… 

VisQuiz: Exploring Feedback Mechanisms to Improve Graphical Perception

— Graphical perception studies are a key element of visualization research, forming the basis of design recommendations and contributing to our understanding of how people make sense of

How Do Viewers Synthesize Conflicting Information from Data Visualizations?

Scientific knowledge develops through cumulative discoveries that build on, contradict, contextualize, or correct prior findings. Scientists and journalists often communicate these incremental

Dispersion vs Disparity: Hiding Variability Can Encourage Stereotyping When Visualizing Social Outcomes

—Visualization research often focuses on perceptual accuracy or helping readers interpret key messages. However, we know very little about how chart designs might influence readers’ perceptions of the

Are We There Yet? A Systematic Review of Visual Perception Knowledge for Visualization Recommendation Systems

A comprehensive schema to collate existing theoretical and experimental knowledge and summarize study outcomes at three levels: between encodings, within chart types, and between chart types is contributed.

Transparent Practices for Quantitative Empirical Research

Transparent research practices enable the research design, materials, analytic methods, and data to be thoroughly evaluated and potentially reproduced. The HCI community has recognized research



No mark is an island: Precision and category repulsion biases in data reproductions

Data visualization is powerful in large part because it facilitates visual extraction of values. Yet, existing measures of perceptual precision for data channels (e.g., position, length, orientation,

The Perceptual Proxies of Visual Comparison

This paper used a staircase procedure to titrate the difficulty of the data comparison to assess which arrangements produced the most precise comparisons for each task, and found visual comparisons of biggest mean and biggest range are supported by some chart arrangements more than others.

Biased Average Position Estimates in Line and Bar Graphs: Underestimation, Overestimation, and Perceptual Pull

It is shown that while position may be a precise form of data encoding, it can also produce systematic biases in how values are visually encoded, at least for reports of average position across a short delay.

Truth or Square: Aspect Ratio Biases Recall of Position Encodings

A pattern of misestimation bias was present for reproductions from memory, suggesting that this bias may arise when comparing values across sequential displays or views, and additional visualization designs that might be prone to this bias are described.

Correlation Judgment and Visualization Features: A Comparative Study

The hypothesis that people attend to a small number of visual features when discriminating correlation in scatterplots is investigated, and it is discussed how visual features provide a baseline for future model-based approaches in visualization evaluation and design.

Perceptual proxies for extracting averages in data visualizations

It is shown that when comparing averages across multiple data Points, even for pairs of data points, these differences vanish, highlighting a critical need to study a broader constellation of visual cues that mediate the patterns that the authors can see in data, across visualization types and tasks.

The Curse of Knowledge in Visual Data Communication

It is shown that when people are primed to see one pattern in the data as visually salient, they believe that naïve viewers will experience the same visual salience, reflecting the curse of knowledge.

Four Experiments on the Perception of Bar Charts

A series of follow-up experiments are described to further explore and explain Cleveland & McGill's results on how different bar chart designs impact the accuracy with which viewers can complete simple perceptual tasks and to propose new hypotheses on the perception of bar charts.

Four types of ensemble coding in data visualizations.

It is argued that a second domain can serve as another strong inspiration for understanding ensemble coding: graphs, maps, and other visual presentations of data.

Assessing Effects of Task and Data Distribution on the Effectiveness of Visual Encodings

This work finds that colored scatterplots (with positionally‐coded quantities and color‐coded categories) perform well for comparing individual points, but perform poorly for summary tasks as the number of categories increases, and suggests improved approaches for automated design.
