The authors present the development of a prototype system called Angur, which is designed and built for visualization of XML documents. There two main motivations of this paper: to allow the users to explore and manipulate XML documents and to display the search results graphically, in two or three dimensions, grouped by topic or category. This prototype employs modern interactive visualization techniques to provide a visual presentation of a set of XML documents. The motivation and evaluation of several design features, such as keyword to concept mapping, explicit clustering, the use of 3-D vs. 2-D, and the relationship of visualization to logical structure are described.
