Bridging Educational Theories of Cognitive Load to Visualization Design and Evaluation
We explore the validity and applicability of educational and cognitive science theoretical frameworks for designing and evaluating climate data visualizations through an exploratory online study using climate change visualizations from the 6th IPCC report. We contribute an interdisciplinary perspective on cognitive processing of visualizations and a discussion of implications for designing and evaluating data visualizations beyond educational contexts.

An Autoethnography on Visualization Literacy: A Wicked Measurement Problem
This autoethnographic reflection on the complexity of defining and measuring visualization literacy is inspired by the growing number of empirical studies in visualization research that rely on visualization literacy as a basis for developing effective data representations or educational interventions. Researchers have already made various efforts to assess this construct, yet it is often hard to pinpoint either what we want to measure or what we are effectively measuring. Continue reading An Autoethnography on Visualization Literacy: A Wicked Measurement Problem
PREVis: Perceived Readability Evaluation for Visualizations
Although readability is recognized as an essential quality of data visualizations, so far there has not been a unified definition of the construct in the context of visual representations. As a result, researchers often lack guidance for determining how to ask people to rate their perceived readability of a visualization. To address this issue, we … Read more
A cognitive load approach to designing and evaluating data visualizations
Visual representations of data are increasingly prevalent, but we lack a detailed theoretical framework to explain what factors make easy or difficult to read and understand; nor do we know how such factors can impact data visualizations’ efficiency as learning material. In this Master’s Thesis, I address this gap by exploring the validity and applicability … Read more
A case to study the relationship between data visualization readability and visualization literacy (position paper)
Only with reliable and relevant measures can we assess how a potential factor affects a reader’s performance; accordingly, only with appropriate measuring instruments can we start to investigate the tight web of interactions between individual characteristics, features of the visual design, and reading tasks requirements. As we slowly progress in our understanding of how people … Read more
Open Questions about the Visualization of Sociodemographic Data
The visualization research community engaged a reflection on how to represent data about people. This work collects a set of open research questions and highlights some future research directions. Access the document on HAL Access the document on OSF Florent Cabric, Margrét Vilborg Bjarnadóttir, Anne-Flore Cabouat, and Petra Isenberg. Open Questions about the Visualization of … Read more
Pondering the reading of visual representations
We draw from the cognitive psychology literature on models of reading text, and describe a knowledge gap for cognitive processes at work when reading visual representations of data.
