[Statcvs-users] visualization from cvs

[Aaron Z. <az...@me...>]

Just to remind people, I'm currently writing a visualization that looks 
at the relationship between code & communication.  Since I have not 
been able to get an archived version of this mailing list, and I dont 
have time right now for screen scrapping off source forge, I ran my 
visualization against statcvs but without the communication.  You can 
find a copy of it at 
http://bonobo.media.mit.edu:8080/~aaron/statcvs.pdf  There are still 
seems to be a rendering error (where people will cross over each 
other), and this pdf is not a screen shot thus loosing the interactive 
exploration of my program, as well as dates.  But I'm curious to get a 
reaction from a similar project (w/o the communication).  I created 
this by looking at each file revision and who owns the code over time.  
Each color represents a person, and the height is proportional to the 
total amount of code they own as time increases (starting from the 
beginning of the CVS archive).  There is some quantization from nearby 
commits to create smoother lines depending on the scaling of the 
x-axis.... but since this is a 2 year few the quantization is decently 
high.  Also this does not include some deleted files that CVS couldn't 
access (gtk-- doesnt have this error but statcvs does).  To combat the 
visual artifact of one person's commit looking like everyone committed 
(since the whole stack rises), you'll see some white lines going over 
the increases... this indicates who committed and is responsible 
(possible for multiple).  The people are in order of color lukasz, 
cyganiak, manschu, jentzsch, farkas, squig.

Is this what you'd expected statcvs?  Does the data look inaccurate, 
and if not, does it reflect what how you thought about the project in 
comparison to statcvs's outputs of itself?

Thanks for any feedback,
