That would match my second guess. I guess the tweaks are what make it
hard to do the actual correspondance (there are 53 circles on the
drawing if I counted correctly, and 156 directory in today's Git for
example). The biggest dirs in number of files today are:

./builtin 99
./t/t5515 128
./t/t4013 144
./Documentation 221
./Documentation/RelNotes 242
. 378
./t 774

The directories at 4e7a2eccc21c902918 (Thu Dec 29 01:31:26 2005 -0800)
were:

./Documentation/technical 2
./mozilla-sha1 2
./arm 3
./ppc 3
./compat 4
./Documentation/howto 8
./templates 12
./debian 14
./t/t4100 14
./t 62
./Documentation 126
. 191

So, t/ would be a nice candidate for the big circle on the left hand
side (small in 2005, but biggest as of now), and ./ would be the one on
its right (used to be biggest, but no longer). Documentation/ is the one
at the top (with subdirs howto/ and technical/ in 2005, and the new
RelNotes/ today). I'm not sure where builtin/ is, it was probably
tweaked too much (it's supposed to be rather big in 2015 and inexistant
in 2005, without subdirs).
