This software is a Processing sketch used to visualize code ownership as fractal figures. The sketch is used to explore the ownership analyses from Your Code as a CrimeScene. The sketch isn't intended to scale to large systems -- it's a free proof of concept.

The algorithm and idea comes from research by D'Ambros and Lanza as published in their paper Fractal Figures: Visualizing Development Effort for CVS Entities.
Run the sketch in Processing. The code has been tested with Processing 4.
When you start the program, it prompts you for a file containing the CSV with the results of an entity-effort analysis. You obtain those ownership metrics via Code Maat.
That's it - the fractal figures will appear together with a color legend to interpret them.
During a visualization, press s to save an image to disk. In case you haven't provided a file with color mappings, the visualization will generate random colors. Just press space to re-draw the image using a new set of colors.
Note that the implementation is quick and dirty (with emphasis on the later). That means, input data isn't validated. In practice it shouldn't be much of a problem - you'll notice fast.
The program has been implemented properly in CodeScene's free Community Edition, which is intended for professional use. Anyway, I still hope that you'll find this simpler sketch useful in its current shape.
