In this blog post, we want to tell two stories: First, we want to explore how visualization can be used to select cancer treatments. And second, we want to tell a more technical story of how you can use exemplars to deal with large datasets that you can’t easily summarize.

Conducting user studies to evaluate visualizations is a popular approach for evaluation. During the pandemic such user studies have migrated to crowdsourced platforms due to restrictions on in-person studies. Do we pay the participants in our studies fairly? Is it our job to do so? Our panel at IEEE VIS 2021, explored the above questions and many more.

Is recording a conference talk really any easier than giving one?

As a research community, we have been using the imprecise term “chartjunk” in situations where other words would be a more precise, and kinder fit. In our manifesto, part of the alt.vis workshop at IEEE VIS 2021, we blur the boundaries between performance art, maintenance, and research as our first steps of putting chartjunk in the trash.

Are you considering grad school? Here are a few steps you can take to maximize your chances. The bad news is that it’s best to start planning and working towards getting into grad school early: I recommend you take first steps some time at the end of your sophomore year in college. The good news is that the process is...

The review process at IEEE VIS hasn’t changed in the last decade. Here I lay out some suggestions to make the process more equitable, open, and to possibly raise the quality of reviews.

Much of the current conducting and reporting on design studies leaves little room for contributions outside of the end tool or technique. An interpretivist approach embraces the messy, subjective nature of design studies and emphasizes the ways in which we can conduct research of this nature with rigor. In this post, we advocate for interpretivist design studies and give three...

Tracking a history of actions of an interactive visual analysis session (i.e., its provenance) has benefits ranging from simple undo/redo, to enabling reproducibility, to making post-hoc analysis of user sessions possible. However, there are no established provenance tracking libraries that visualization developers can use with their web-based tools. This blog post introduces Trrack – a web-based library designed for easy...

Crowdsourcing is a popular method for conducting quantitative studies, yet up to now, the types of studies that were run on crowdsourcing platforms is narrow. In this blog post, we describe a method to evaluate complex visualization techniques in a crowdsourced setting, which we developed for a 2020 CHI paper on evaluating multivariate network visualization techniques.

tldr: As states are navigating the influx of COVID data, they are using dashboards to communicate with their constituents. Although many states are doing a good job at collecting and sharing data in open data portals, dashboard quality varies a lot across states, and some have considerable room for improvement.

tldr: Using dashboards comes with risks: they leave out critical context by over-simplifying and hence give false certainty. A more nuanced approach including interpreation by experts, and showing multiple perspectives is needed when visualizing data for something as complex as the COVID-19 pandemic.

tldr: We're starting a blog to communicate about our research and share our thoughts on data visualization!
