We presented an interactive time-aware visualization prototype, LifeCircle, to help microblog users to visually retrospect their life statuses. By exploring and analyzing long-term microblogging post data, we summarized annual topics, monthly keywords, monthly sentiments, and microblog activity to generate a compact radial visualization for a certain microblog user. We implemented a prototype system for Sina Weibo, the largest Chinese microblogging service. Case studies demonstrated the usefulness of our prototype.
