For all the folks at Javaranch there's a tool that visualises the complexity of your software (ones built in Java)? We have just released the first public version of CyVis. CyVis is a software metrics collection, analysis and visualisation tool for software built using Java. It enables developers to identify complex part of their software very easily. CyVis collects data from java class or jar files hence there is no need for the actual source code. Once the metrics are collected, the statistical information is shown in a way that enables you to immediately detect which part of your software is complicated and which is not. CyVis can either be integrated with your Ant script or used in command interface to generate reports. It also has a GUI Interface which we consider to be of great help to its users. You can be downloaded this tool from the CyVis Homepage.
