Read, Critique, or Sketch? Investigating Alternative Visualization Literacy Assessment Modalities
Zach Cutler, Lily W. Ge, Matthew Kay +3
Visualization literacy is a multifaceted construct encompassing skills and competencies, such as decoding data, constructing charts, and identifying design flaws. Yet, assessments…
Touching or Chatting: The Utility of LLMs and Tactile Charts for Learning about Complex Chart Types by BLV Individuals
Tingying He, Maggie McCracken, Daniel Hajas +2
Visualizations are central to communicating data, yet blind and low-vision (BLV) people often lack support for understanding chart types---knowledge that is essential for interpret…
Should We Dangle a Carrot? The Effect of Performance-based Incentives in Visualization Experiments
Abhraneel Sarma, Matthew Kay, Sheng Long +2
A perennial research question in visualization involves identifying which visual encodings for a particular dataset are most effective for users in performing a specific task. The…
Evaluating Encodings for Bivariate Edges in Adjacency Matrices
Jorge Acosta-Hernández, Alexander Lex, Tingying He
We present the first empirical evaluation of techniques for encoding distributions of quantitative edge values within adjacency matrices. In many real-world networks, edges represe…
Reflections on Traceability for Visualization Research
Jen Rogers, Derya Akbaba, James Scott-Brown +2
Decades of advocacy for reproducibility and replication have advanced open, transparent practices in the sciences. However, traditional notions of reproducibility fit poorly with d…
Using Tactile Charts to Support Comprehension and Learning of Complex Visualizations for Blind and Low-Vision Individuals
Tingying He, Maggie McCracken, Daniel Hajas +2
We investigate whether tactile charts support comprehension and learning of complex visualizations for blind and low-vision (BLV) individuals and contribute four tactile chart desi…
