Application of Helix Cone Tree visualizations to dynamic call graph illustration

We describe a tool that enables users to record and visualise runtime behaviour of software applications developed in Java. The execution trace, stored in the form of an XML le is visualized using 3D call graphs that are an extension of the Cone Tree infor- mation visualisation technique. This tool gives the user the ability to create several call graph views from a program's execution trace, providing additional representations of the program execution to both novice and expert programmers for the purposes of program execution analysis.
