This is interesting enough data, but it doesn't really prove anything. As you can see, the turn "django" was at the 1.0 mark before it even really started, so you have to take that into account when looking at the numbers.
Even with that correction, it does seem to put Django in a slight lead, but it also shows that it has had a much steadier growth (assuming jazz references would have stayed steady and all new growth is related to the framework).
