People from Georgia Tech, INRIA, University of Stuttgart, and other institutions have put together a comprehensive dataset of all papers presented at Vis/VisWeek/VIS since 1990. This was first collected for a set of visualizations last year, but has been updated with the 2014 data. They intend on keeping it up to date.The dataset contains not just … Continue reading Link: Visualization Publication Data Collection

Link: Disinformation Visualization

June 3, 2015
By

In his piece Disinformation Visualization: How to lie with datavis, Mushon Zer-Aviv makes some interesting points about how framing the same data differently in visualization can make a big difference. Using the example of the abortion debate, he shows the usual chart tricks, cherry-picking, subsetting, etc., that is done to make the data support a particular story. This is … Continue reading Link: Disinformation Visualization

Report: EuroVis 2015

June 2, 2015
By

I attended EuroVis 2015 last week in Cagliari, Sardinia. This is the second-most important conference in the academic visualization world, and there were plenty of good sessions to choose from (full and short papers, state-of-the-art reports, and industry sessions). As usual, this is a highly subjective and incomplete report. I did not see anywhere near all … Continue reading Report: EuroVis 2015

Paper: An Evaluation of the Impact of Visual Embellishments in Bar Charts

Information graphics often use variations and embellishments of standard charts that may distort the way people read the data. But how bad are these distortions really? In a paper to be presented at EuroVis this week, Drew Skau, Lane Harrison, and I tested their effects in an experiment. Based on a survey of common infographics … Continue reading Paper: An Evaluation of the Impact of Visual Embellishments in Bar Charts

EuroVis Running Club

May 20, 2015
By

I’m organizing a very informal running club at EuroVis next week. If you’re attending the conference, don’t forget to bring your running shoes and leave your excuses at home. This is even less organized than than the VIS running club. I’m not going to have you fill out a form. Instead, just drop me an … Continue reading EuroVis Running Club

Feedback Loops for Better Talks

Feedback loops are a common concept in engineering. When it comes to giving talks, academics would do well to apply some of the thinking behind them to improve their output by observing how it deviates from the desired one, and making changes to adjust it. I’ve been to a number of conferences lately that had a … Continue reading Feedback Loops for Better Talks

Video: The Danger of Glitziness

April 29, 2015
By

Wayne Lytle created this video about the Viz-O-Matic that provides lots of tools to make visualization glitzier. It’s a nice little spoof, and a throwback to the computer graphics of the early 1990s (it was made for SIGGRAPH 1993). This video was brought up in a discussion about storytelling at CHI last week, though I … Continue reading Video: The Danger of Glitziness

Conference Report: CHI 2015

April 27, 2015
By

Last week, I had the pleasure of attending the CHI 2015 conference in Seoul, South Korea. CHI technically stands for Computer-Human Interaction, but it has become a name rather than an acronym in recent years. And CHI’s scope is very broad, it covers many areas that are not strictly part of HCI (Human-Computer Interaction – … Continue reading Conference Report: CHI 2015

Link: The Power of Wee Things

April 22, 2015
By

Lena Groeger (of ProPublica) has written a beautiful piece about the Power of Wee Things. She talks about using small things, multiples, and units to display data and get people interested. The article goes through many, many examples covering many different areas and ideas. She also gave a great talk on the topic at OpenVis 2014. On a somewhat related … Continue reading Link: The Power of Wee Things

Paper: ISOTYPE Visualization – Working Memory, Performance, and Engagement with Pictographs

Paper: ISOTYPE Visualization – Working Memory, Performance, and Engagement with Pictographs

Unit charts are not common in visualization, and they are often considered a bad idea. The same is true for using shapes other than rectangles. Neither is based on much actual research, however. In a new paper, we look at the specific example of ISOTYPE-style charts – and find them to be quite effective. I have written about ISOTYPE … Continue reading Paper: ISOTYPE Visualization – Working Memory, Performance, and Engagement with Pictographs
