Embellished charts are common in information graphics. But are embellished bar charts actually harder to read than plain ones? In a short paper to be presented at EuroVis next week, Drew Skau and I present a study that looked into this question. This is a follow-up to Drew's earlier paper on embellished bar charts that looked only at […]

It's not a secret that I think that we need to ask some harder questions about the foundations that we're building visualization on. In a paper to be presented at the BELIV workshop at VIS next week, I'm making the case for that more extensively than I have so far. The full title of the paper is An Empire Built […]

Related to my last post, here's a new paper that just arrived from Rachidi Kotchoni and Dalibor Stevanovic, "Forecasting U.S. Recessions and Economic Activity". It's not non-parametric, but it is non-linear. As Dalibor put it, "The method is very simpl...

Nonparametric K-nearest-neighbor forecasting remains natural and obvious and potentially very useful, as it has been since its inception long ago. [Most crudely: Find the K-history closest to the present K-history, see what followed it, and use that a...

How do we read pie charts? Do they differ from the even more reviled donut charts? What about common pie chart designs like exploded pies? In two papers to be presented at EuroVis next week, Drew Skau and I show that the common wisdom about how we read these charts (by angle) is almost certainly wrong, and that … Continue reading A Pair of Pie Chart Papers

Presentation is often considered a part of visualization, but what does that mean for the kinds of techniques we use? Are they the same as used for analysis? What criteria should we use to pick them? In a new paper, I discuss a class of techniques I call presentation-only. The paper is accordingly titled Presentation-Only Visualization Techniques, and it just … Continue reading Paper: Presentation-Oriented Visualization Techniques

I’m very happy to finally be able to announce our paper on the connected scatterplot technique. It describes the technique, provides some historical perspective, and most of all looks into how easy to understand and engaging the technique actually is. The connected scatterplot isn’t really known in visualization, but has gotten some interest in journalism. … Continue reading Paper: The Connected Scatterplot for Presenting Paired Time Series

Reproducibility is hard. It will probably always be hard, because it’s hard keeping things organized. I recently had a paper accepted at G3, concerning a huge set of sample mix-ups in a large eQTL study. I’d discovered and worked out the issue back in December, 2010. I gave a talk about it at the Mouse […]
