报告题目:Declarative Data-Driven Chart Animation


Animation can bring data to life. By animating data visualizations, viewers can be engaged in ways other methods may not be able to. However, there are many challenges in adopting existing tools in authoring visualization animations, which are expressive and consistent with the underlying data patterns: (1) lack of the relationship between data, visual marks, and time; (2) lack of a visual description manner to facilitate both the understanding and authoring of visualization animations; (3) lack of an intuitive authoring mechanism which can ease the learning curve of the tools. To address those issues, I will first introduce Canis, a high-level language for data-driven chart animations. It provides simple yet precise syntax to describe and create various visualization animations in a data-driven manner. To facilitate the understanding of the animations and lower the barrier for novices, I will propose CAST, which is an interactive authoring tool based on Canis. It introduces a set of visual specifications to explicitly describe the animation process. The visual specification exposes animation properties as visual components and supports direct manipulation to adjust the animation. Meanwhile, it incorporates data-driven auto-completion for both keyframe and keyframe sequence to reduce the manual burden, and guarantee the consistency between data and the result animation.


Tong Ge is a PhD student from Shandong University, co-advised by Baoquan Chen and Yunhai Wang. His research focuses on helping humans more effectively and systematically designing data-driven chart animations. For more details, please refer to

报告题目:Understanding Data Accessibility for People with Intellectual and Developmental Disabilities (IDD)


How do people with IDD interpret data differently than non-disabled population? In this talk, I will present findings on both populations’ chart preferences and the different strategies they use to make sense of data. I will share a series of accessible visualization design considerations coming out of a web-based study, and reflect on our best practices that may have created barriers to effective use of data.

Keke Wu is a PhD student at the University of Colorado Boulder. She works with Dr. Danielle Albers Szafir at the VisuaLab. Keke is interested in making data visualization accessible to people with various cognitive abilities particularly through multimedia design and storytelling. She uses a combination of quantitative and qualitative methods to solve real-world problems,  design better technologies, and empower underrepresented groups. Besides being a researcher, Keke is a visual artisit and storyteller. Personal Page:
