I think, from reading the chart, that ExtJs is pretty well stablished but loosing steam, and the new frameworks picking up steam, specially AngularJS.

Now these trends focus on a world wide searches. If you look closely at the detail, the number of search for extJs in China, pretty much take the 90% of the searches. And in the U.S. extJs has practically no prescence.

If you look at the detail for AngularJS, most of the searches are in California, New York and India.

So it is really not the best trend analysis, but it does put the power of China into perspective.
