Yahoo has published a few details about the up and coming additions to their YUI Charts library named YUI3.  In particular, I found this intriguing:

The modularity of the Charts component within the Flash Player (our current rendering engine of choice) is fully paralleled in its JavaScript wrapper. From the JS developer’s point of view, you are working with a set of JS components, with all method calls, display list changes and property assignments seamlessly transmitted to Flash and back. (This abstraction will be even more crucial when we move beyond a single rendering engine.)

Move beyond a Single Rendering Engine?  Could this mean that they’ll be moving beyond Flash charts and into JavaScript/Canvas charts? Maybe Silverlight?  Who knows.  What would you like to see?
