Hi! I am now an associate professor at Shenzhen University. I lead the Spatial Creative Intelligence & Interaction (SCII, /skaɪ/) research group in Shenzhen University. The passion of our group lays in the AI generation of creative spatial visualizations, mainly stylized maps and map-related spatial applications. Our latest work towards our passion are Layered Image Vectorization, Image-space Collage. I received my Ph.D degree in Computer Science from Peking University in 2017. Before, I have several works in general visualization and visual analytics: (1) design intuitive visualization, e.g., Winglets, Sticky Links, Interaction+. (2) understand visual designs, e.g., Visual Information Flow in Infographics, JND Modeling in Charts; (3) address urban problems in visual analytic manner, e.g., a series of trajectory analysis methods.
: ) I am looking for graduate students (of CS Master Program) who share a strong interest with what I am doing! Please contect me with your resume reflecting your passion.

Selected Projects

Layered Image Vectorization via Semantic Simplification
CVPR Conference on Computer Vision and Pattern Recognition, 2025.
[Paper (41.8 MB)]
[Project Homepage]
We present a layered image vectorization technique with image simplification, that reconstructs the raster image as layer-wise vectors from semantic-aligned macro structures to finer details.

A Versatile Collage Visualization Technique
Arxiv 2025
[Paper (4.6 MB)]
[Project Homepage]
We introduce a versatile image-space collage technique designed to pack geometric elements into a given shape, and demonstrate its diverse visual expressiveness in various applications.

Creative Blends of Visual Concepts
CHI Proceedings of the 2025 CHI conference on human factors in computing systems, 2025.
[Paper (25.3 MB)]
We Creative Blends, an AI-assisted design system that leverages metaphors to
visually symbolize abstract concepts by blending elements from two distinct visual concepts into a single

Sticky Links: Encoding Quantitative Data of Graph Edges
PacificVisTVCGIEEE Transactions on Visualization and Computer Graphics, 2024.
[Paper (0.4 MB)]
[Source Code (Python)]
[My Talk at PacificVis 2024 (32.4 MB)]
In this work we propose a new edge drawing for node-link diagram, Sticky Links. Using the metaphor of stickiness, sticky links can be used for expressive edge quantatitive encoding.

Enhancing Static Charts with Data-driven Animations
TVCGIEEE Transactions on Visualization and Computer Graphics, 2022.
[Paper (1.82 MB)]
[Project Homepage ]
[Source Code (Javascript)]
In this work we propose data-driven animation to bring static charts to life, with the purpose of encoding and emphasizing certain attributes of data, specifically of non-temporal data.

Modeling Just Noticeable Differences in Charts
InfoVisTVCGIEEE Transactions on Visualization and Computer Graphics, 2021.
[Paper (2.1 MB)]
[Experiment Data ]
[My Talk at VIS 2021 ]
In this work, we model the perception of Just Noticeable Differences (JNDs) in charts with two variables (intensity and distance) and find that JND grows as the exponential function.

Exploring Visual Information Flows in Infographics
CHI Proceedings of the 2020 CHI conference on human factors in computing systems, 2020.
