Developed by the HCI Lab at the University of Maryland, SocialAction is a social network analysis tool that integrates visualization and statistics to improve the analytical process.SocialAction has been used in different projects by helping users make discoveries and dramatically speeding insight development. In the images shown here, SocialAction was the key visualization tool in mapping the social network of the U.S. Senators voting patterns in 2007, after Democrats took control. Republicans (red) are on the right and Democrats (blue) are on the left, with two Independents (maroon). Links indicate the similarity of voting records, revealing that Democrats had stronger party loyalty during 2007. Four Republican Senators from Northeastern states often voted with Democrats. McCain and Brownback were campaigning for the Presidency and did not vote often enough to be connected.
