Wow. Looking at http://agilevisualization.com/AgileVisualization/QuickStart/0101-QuickStart.html http://agilevisualization.com/AgileVisualization/QuickStart/... and http://agilevisualization.com/AgileVisualization/Roassal/0104-Roassal.html http://agilevisualization.com/AgileVisualization/Roassal/010..., this tutorial looks infinitely more useful than the original post. Partly because it actually shows pictures of the visualizations you get for a given piece of code.
