For the 2012 State of the Union Address, my team at Turner Broadcasting built a project called Tweet of the Union (I take 100% credit for the name :). We consumed Twitter feeds from all House and Senate reps, and provided visualizations to show who was participating in conversations, broken out by political party, age, tenure, gender, and home state. The responsive page was featured in the CNN iPad app during the State of the Union.
With a quick 9-day turnaround on this project, I buckled down with the very talented Miss Lauren Langley to sketch out possibilities for the interface and visualizations. We determined the most effective visualization options given our timeline and subject matter, and got right into production.
We arrived at three main types of visualizations- a horizontal bar for discrete comparison (party, gender), a radial bar graph for gestalt interpretations of range data (age, tenure), and a map of the United States for Tweet volume per-state. The bar and radial graphs were constructed using HTML and CSS, and the map utilized open-license SVG.
The resulting app contained a filterable list of Tweets, filter selection buttons, and the aforementioned visualizations.
