For a straightforward data visualization talk, Fernanda and Martin actually received quite a lot of laughs. At the start, they showed the intrinsics of human anxieties through their visualization "Web Seer" (original post at infosthetics). In addition, they demonstrated a new "hand-crafted" interface called "Twitter Trending Topics in the U.S." that compares some of the trending Twitter topics to the race of the people posting them. Lastly, they gave a sneak preview of a visualization titled "Visualizing Conversations at Twitter", which sorts different conversations by hashtags and reveals the overlapping and outlying hashtags within political conversations.
