Plot a Graph: # Portable Apps Available over Time

It would be interesting (or not) to see a graph that shows the number of official portable applications available over time (say on a monthly basis). Just purely out of curiosity.

I was just looking at the list a moment ago, seeing what apps might need updating, thinking to myself, "Wow, this list is getting pretty huge. I remember back in the good old days when I barely had to scroll the screen!"
