We developed this project in partnership with the agency JWT in Brazil and it served as a new demo of the social media and real time technologies we are currently developing at Zauber.
(note: only two weeks ago we also launched another demo of our technology by publishing a Google Maps + Twitter + Foursquare mashup that creates a real-time map visualization of foursquare check-ins shared on Twitter.)
This new visualization experiment for Brazilian elections proved how strong Twitter is on Brazil and how users are engaging with a new wave of digital projects that involve real-time user generated content, metrics and visualizations. By visiting http://experimento.jwt.com.br users could check the trend on Twitter for mentions of the three most important candidates and explore a visualization of twitter avatar's users filling the picture of each candidate with a velocity based on the amount of content being generated.
Let us share with you some key statistics about the results of this project. Let's start by taking a look at this infographic we created to show how trends evolved during the day of the election:
