It didn’t take long after the Superbowl ended for there to be an awesome visualization of all the Twitter activity during the game. The visualization uses CartoDB’s Torque library to show over 1 million tweets in just 6 hours.

Yesterday, Knight Foundation announced that Vizzuality and CartoDB have received a grant to help build an open source tool for journalists that will enable better storytelling with maps online. We have long been advocates of storytelling using maps and data visualization and this grant will allow us to help make it easier for everyone. As part of the Prototype Fund, our project aims to simplify the process of combining narratives, maps, and interactions into a single web page.

Mapping historic and temporal data can be challenging. A lot of times you need to think about clever ways to aggregate or filter that data so you can highlight and tell a story without losing too much of the overall picture. But with our recent release of Torque maps, we expanded your options for mapping temporal data, giving your viewers the ability to play, pause, and backup animated data in order to explore how the data changes over time. We just pushed an awesome little enhancement to Torque visualizations: cumulative visualizations.
