In this project we present our exploration of several visualization techniques which use motion as the primary visual element for depicting online discussions. Visual attention appeals most strongly to motion. Since motion changes the immediate environment conditions, it is more likely than static visual cues to attract our attention. Motion is dynamic and vibrant; it is intuitive and suitable for representing large-scale online social data such as online discussions. Our designs and findings shed light on choosing the mappings between motion and social characteristics for creating intuitive and legible visualizations.
