Hi, I'm Zhongzheng Xu 👋

I love

I am currently a first-year Ph.D. student at University of Maryland, College Park under the guidance of Dr. Fumeng Yang.

Before I joined UMD, I received my Master's degree in Computer Science at Brown University.

At Brown, I worked under Dr. Jeff Huang at Brown HCI Lab. We are exploring the effect of visualizations on people's self-reflection over their personal text data.

To pronounce my name, think of it like "John Jane Shoe". In my free time, I like being a barista and photographer.

Exploring the Capability of LLMs in Performing Low-Level Visual Analytic Tasks on SVG Data Visualizations

Zhongzheng Xu, Emily Wall

2024 IEEE Visualization and Visual Analytics (VIS) April 29, 2024

Pages: 126-130

Data visualizations help extract insights from datasets, but reaching these insights requires decomposing high level goals into low-level analytic tasks that can be complex due to varying degrees of data literacy and visualization experience. This research explores how large language models can perform visual analytic tasks directly on SVG-based visualizations.

Let's Get Vysical: Perceptual Accuracy in Visual & Tactile Encodings

Zhongzheng Xu, Kristin Williams, Emily Wall

2023 IEEE Visualization and Visual Analytics (VIS) October 21, 2023

Pages: 16-20

This research explores the effectiveness of tactile data encodings using swell paper compared to visual encodings displayed with SVGs for data perception tasks. The study establishes a novel tactile encoding hierarchy and provides empirical evidence for the perceptual accuracy of tactile encodings.
