Good question!

"Growth" was probably the wrong word.  I should have said "D's Evolution".

The x axis is obviously time, which you probably guessed.

I think the y axis may be "#of releases times 0.001".  So the 0.05 line 
would then represent the 50th public release version of D.  Anyway it 
looks for the most part like each marker is a fixed y delta from the 
previous one.  So the y-axis is probably "#of release times [some 
constant]"
There is one place in the middle that looks to be more than 1 step above 
the previous point, but that may just be a data entry error.  Or maybe 
there was a release in there that was pulled because it was too buggy?

And then I think D2 is just offset downward by a bit so as to be visible.


I'm pretty sure the data was taken directly from the change logs on 
digitalmars.com.
