MSR-TR-2001-94, published in October 2001 by Andrew Fiore and Marc A. Smith. In this paper, we describe visualizations of Usenet created by applying treemap techniques to the data generated by tracking a large collection of newsgroups over an extended period of time. These images illuminate several major structures and suggest a method for further exploring large-scale social cyberspaces.
