Basic instructions

Moving the visualization around

left-click and drag outside of the core-visualization to pan
right-click and drag to zoom
middle-click to 'zoom to fit'

Playing with the data (for the JHowDraw-demo)

click the PMD-button to import PMD-findings
select a different ViewPoint (e.g. Cyclomatic Complexity)
change the Sensitivity Multiplier to analyse the sensitivity of this metric (notice the Sensitivity Intervals change)
right-click org.jhotdraw.geom to drill down to package-level
click the MetricValue-column header to sort (notice DoubleStroke.java contains the highest CC-finding - 21)
double-click (any) DoubleStroke.java to see all findings for this file
double-click (any) Confusing Ternary to see all classes which contain this violation
double-click (any) org.jhotdraw.draw to see all findings for this package

Don't hesitate to contact Mark in case you'd like to see a visualization of your own (or a large open source) codebase.

Known issues

This demo gives an impression of the Complexity Map visualization, but is not bug-free, nor feature complete.
The following bugs are known for the demo v0.1:

Checkstyle-import does not work in Demo-mode - requires source-code
Prefuse log gives a console-error on initialization - log-directory is unavailable from where the application is started

Your feedback is appreciated.
