This demo shows a system called Dust and Magnet (DnM) that is a general purpose data visualization system. DnM represents data items as iron dust. Each attribute of the data then is a magnet. The system is implemented on a large multi-touch display where the analyst can deploy magnets and drag them around the view. Data points will then be attracted more strongly or weakly depending on that data item's value of the attribute represented by each magnet. This system provides a very hands-on, visceral data exploration experience.

Followers are Twitter's most basic currency. Building an audience of followers can create access to a network of social ties, resources, and influence. Yet, little is understood about how to grow such an audience. We examine multiple factors that affect tie formation and dissolution over time on the social media service Twitter. We collected behavioral, content, and network data approximately every three months for fifteen months and compared the relative contributions of 22 variables from each perspective for predicting link formations in online social networks.

Chitra is a mobile platform that empowers community health workers to fill this gap between government healthcare delivery and patients' lived realities.
