The problem with this is that the releases were not made at fixed intervals. 2.6.0 -> 3.0 represents more than double the amount of development time as 2.4 -> 2.6, yet they get roughly the same amount of horizontal space on your plot.
I think it would be much more interesting to scale by release dates, so that the gap between releases is proportional to the time between them. I suspect you'll see a very different shape.
Furthermore, looking at the raw data, you gave 2.4.37 (released in 2008) a lower release number than 2.6.0 (released in 2003), which seems odd.
