To visualize Twitter streams during the 2012 French presidential election, we developed a web-based visualization called Bubble-t [3]. It addresses the challenges of real-time visual update by using a particle system to fill in a bar chart. Each particle is a new piece of information that we refer to as a “token” (in this context, a Tweet). Each bar corresponds to a presidential candidate. Therefore, once a tweet is sent about a candidate, it is transformed into a token that is thrown into the candidate’s bar. By accumulation, the columns are progressively filled in by the tokens. When a column is full, the n tweets that first arrived are flushed out of their column. We mapped the Twitter user’s avatar to the token for additional informations and to further engage viewers. A static bar chart at the bottom captures all tweets during two different time periods (7days or 24hours). The application received an award at the Google Dataviz 2012 challenge. Up to 81 273 unique visitors browsed the website in 6 months time. The average visit duration was 4min 21s, which is long. We received positive feedback from Twitter users with more"than 1 800 tweets embedding the URL. This work also received attention from some national and authoritative media such as newspapers and radio. We also informally observed unexpected reaction from users. When the visualization was publicly presented, the audience in the room sent tweets, not only to test the system but also to show or see their own avatar inside the chart.

Bubble T, is an instance of Visual Sedimentation.
