We are a team of visualization researchers at the University of Utah. Our interests include the process of designing and developing visualizations, visualization for biology, visualization frameworks, and, more generally, visualization of big, heterogeneous, and complex datasets.

VDL is part of the Scientific Computing and Imaging Institute and the School of Computing.

Blog Post: Can We Guess Why you Selected Something in a Scatterplot? 28 Oct 2022
Selections are a key interaction in data visualization. They are used for highlighting and as the starting point for subsequent actions, including filters, group assignments, etc. Capturing the intent – WHY were these items selected? – can be used to help users refine their selections and to keep a meaningful history of the analysis process. This post discusses our paper on techniques to capture such intents.

Blog Post: Data Hunches – Recording and Communicating Personal Knowledge in Visualizations 11 Oct 2022
Have you ever looked at data visualization and thought: that doesn't look right. Maybe you knew more about the data than is actually contained in the dataset. Did you then remember that hunch throughout your data analysis process, impacting your judgment and interpretation of the data? That thought, whether you were aware of it or not, possibly impacted your interpretation. Especially if that hunch is based on knowledge you have about the data, it would be useful to externalize that hunch, so others can learn about it and also consider it in their analysis. However, current visualization methods do not support this. In this blog post, we dive into how we came up with data hunches to describe personal knowledge brought to data analysis. We explore methods and designs to record and communicate data hunches through visualizations explicitly.

Blog Post: Loon – Finding the Right Cancer Drug with Microscopy and Visualization OR How to use Exemplars to Effectively Browse Large Complex Data Sources 27 Apr 2022
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.

Overview of Loon interface that includes linked multi-view visualizations with various charts and images of cancer cells.
