A growing area of content creation in which information is represented graphically and often
interactively. This can be used for subjects as diverse as an analysis of a speech by the president and the popularity of baby names over time. While it has deep roots in academia, data visualization has begun to emerge on content sites as a way to handle the masses of data that are being made public, often by government. There are many tools for data visualizations, including Seattle-based Tableau and IBM’s Many Eyes. Data visualization should 1) tell a story, 2) allow users to ask their own questions and 3) start conversations.
