Digg Swarm is part of a set of interactive visualizations from Digg Labs that look beneath the surface of the Digg community's activities, one of the most active online social communities on the web. These visualization tools are extremely interesting to use and truly striking for observing the level of activity within Digg. They are the result of a collaboration with Digg partner Stamen Design.In Digg Swarm circles are drawn for stories as they're dugg. Diggers swarm around stories, and make them grow. Brightly colored stories have more diggs. The visualization has three modes: all activity, popular, and newly submitted stories.
