Abstract: 
In this work, we propose a visual analytic system for analyzing events of Weibo, a Chinese-version microblog service. We build a system which consists of two interfaces: a web-based online visualization interface for public users and an offline expert visual analytic system which wraps the online one and provides additional analysis functions. The online interface provides an intuitive and powerful retweet tree visualization which inspires users' creativity. The expert system adopts public users' analysis results collected from the web interface, and can visualize and analyze Weibo events to a deeper extent.
