Oh dashboards… dashboards… what are they? For some, they are just ugly examples of bad visualization design (speed dials anyone?). For others, they are a first citizen of the data visualization world that deserve to be learned, studied, and understood.
To dig into this debate, we have Lyn Bartram of Simon Fraser University and Alper Sarikaya of Microsoft Power BI on the show to talk about an exciting research project they developed. Their research seeks to build a better picture of what dashboard are and how they are used “in the wild.” The results are summarized in a paper they wrote with their colleagues from Tableau and Honeycomb.io: What Do We Talk About When We Talk About Dashboards?
On the show we talk about how the project got started, what they discovered by analyzing a large corpus of dashboards, and the many ramifications of their research.
We have Steve Haroz on the show to talk about visual perception in visualization. Steve is a research scientist at Saclay, France near Paris (AVIZ) where he studies how “the brain perceives and understands visually displayed information like charts and graphs.”
Steve is also a very active figure on Twitter, where he is frequently asked to comment on visual perception problems in visualization.
On the show, we talk about what vision science is, practical examples of the use of vision science in data visualization, and how to use visual science to make predictive decisions about our data visualization designs.

Sheelagh Carpendale is Professor in the Department of Computer Science at the University of Calgary, where she leads the Innovations in Visualization (InnoVis) research group. Sheelagh is one of the most prominent figures in visualization research and, this week, she joins us to discuss the research taking place in her lab, as well as her innovative ideas about all sorts of information visualization. Sheelagh is renowned for taking a much more holistic view of visualization than usual; she emphasizes interaction, visualization beyond the confinements of desktop displays, and the use of design, qualitative research, and psychology. On the show we talk about the uses of sketching in data visualization, the concept of “active reading” of visualizations, and the standard data viz ideas that are holding us back.

In this episode we have Karen Schloss on the show to talk about color. Yes, color! Karen is Assistant Professor at the University of Wisconsin Madison where she conducts research on the effective uses of color in visualization and everyday tasks.
Karen walks us through the intricacies of color: explaining how it works and why it is so hard to get right. We also discuss the infamous rainbow color map, the association between colors and meaning, the tools developed in her lab, and her fascinating research on coloring trash bins!
Michelle Borkin is Assistant Professor at Northeastern University where she studies the use of visualization in science research, in particular how it impacts human perception and cognition. On the show we talk about how the data viz community can better support the work of scientists, her popular research on data visualization memorability and, of course, the infamous data viz dinosaur.
We have Jarke Van Wijk on the show this week. Jarke is a professor of visualization in the Department of Mathematics and Computer Science at Eindhoven University of Technology and an important historical figure (shall we say legend?) in visualization research.
Many amazing innovative techniques have been developed in his lab, including the widely adopted squarified treemaps (treemaps optimized to use rectangles as close as possible to squares)and hierarchical edge bundling (a technique to bundle the links of a graph together).
In this episode we hear the stories behind many of the innovations developed by Jarke and his group. Jarke also speaks to us about how to make cool stuff; the relationship between design, engineering and research; and artistry in visualization.
Enjoy the show!

Isabel Meirelles is Professor in the Faculty of Design at OCAD University in Toronto, Canada. She is the author of Design for Information, a lovely data visualization book featuring pages of beautiful illustrations and loads of data visualization science. On the show we talk about how Isabel came to write the book, how she designed its content and structure, and how it is now being used for teaching.
We also talk about Information Plus, the data visualization conference she co-organized and took place last June in Vancouver, Canada at Emily Carr University. The conference brought together a whole host of amazing speakers and gained tons of attention from the Twitter-sphere.
Enjoy the show!
