Opinion leaders have great influence in social networks. When influential events occur, experts may be concerned with the opinion flow of the event from social networks. Therefore, the trend of events during a time interval should be explored using a specific visualization tool. However, designing an intuitive and interactive visualization tool from a time-varying data is still a challenge. For example, major topics are commonly edited by opinion leaders on social networks, and people attracted by opinion leaders join the discussion by commenting on the post. This process is involved in hierarchical-level commentary, which increases/decreases in volume with time. Nevertheless, exploring commentary properties using traditional visualization techniques is also a challenge for users. In this paper, we propose TopicWave, a visualization tool that combines ThemeRiver Graph (time-varying visualization) and Sunburst (hierarchical data visualization) to visualize the trend of comments on a post in Facebook. TopicWave can also clearly present hierarchy and time-varying trend of comments on a Facebook fan page and provide an intuitive and interactive visualization design.
