Yueyu Fu & Hong Zhang School of Library and Information Science Indiana University, Bloomington Email {yufu | honzhang} @indiana.edu April 30, 2003 Abstract Email has become one of the most widely used computer applications. As the number of emails we exchange increases at high rate, the number of uses for email increases. Email data patterns may give us other useful information such as personal activities. However, there is no proper visualization tool which can meet this purpose. Our goal is to explore working activity involved in email communication using Treemap algorithm. The results show that the Treemap layout can successfully present the various activities involved in the email flow.
