Scale is based on the average worldwide traffic of jQuery in all years. Interesting!
I think this says it all, jQuery is certainly the most popular! :) Ps – it was hard to match prototype because it’s such a popular word so I used prototype js which is what you would type into Google to find it anyways.

How its calculated
You might have noticed that the scale changes on the Y-axis for different searches. How is the data scaled?
The numbers you see on the y-axis of the Search Volume Index (which you can see after you’ve signed in to your Google Account) aren’t absolute search traffic numbers. Instead, Trends scales the first term you’ve entered so that its average search traffic in the chosen time period is 1.0; subsequent terms are then scaled relative to the first term. Note that all numbers are relative to total traffic.
