Ah, you are right, I didn't analyse the graph enough, I thought
percent would show what you described above, obviously it doesn't
though as the values don't add up to 100%. Even so, I think this is a
better graph:

Since it shows users that regularly use the package, instead of user
that have it installed. Considering that these days distro's have a
lot of stuff pre-installed if you go with the "coders packages" the
usage votes give a better picture than looking at who has it installed
(which includes people that don't use the package at all). That graph
shows that in the end of 2006 SVN became more popular than CVS,
whereas the one from Teemu (http://tinyurl.com/4vpqzg) does not show
that, probalby because a lot of people have it installed, but don't
use it.
It would be interesting if we could link the grow spurts from
http://tinyurl.com/4hu2cn to programming-related events, something
that might have caused people to suddenly use a VCS a lot more (for
example the one in CVS's line from 05-2007 till 07-2007).
