ContactTrees: Egocentric Visualization of Social Interactions

A topic of great interest in social-science research is the study of how people connect and interact with one another, in which network visualization is often used to show relations among people and activities. Previous network visualization, however, has not demonstrated how relationships form and change based upon interactions among actors, and how networks and ties vary by contact attributes. In this work we present ContactTrees, a new Egocentric visualization technique designed to better capture the dynamics of social relations and interactions, and to facilitate instant comparisons of interpersonal ties and contacts. The technique is based on a botanical tree metaphor. The tree is easy to construct and the resulting tree-like visualization can display many properties at both tie and contact levels, a key ingredient missing from the conventional techniques of network visualization.
