JavaScript libraries to work with HTML5 Canvas

[graha]

Hi,
I have just started using JavaScript and JS frameworks for Canvas and I need help. I have an assignment to find the best framework(s) for these tasks:
- good drawing perfomance(ecpecialy in drawin huge amount of data given in JSON and SVG),
- works with JSON,
- works with SVG and
- can be useful to draw interactive objects(object that can be moved, resized...)

Basicly, I need i library or libraries to draw interactive objects on Canvas. These objects(icons, lines...) are described in SVG and JSON and my aplication need to parse them and draw them on Canvas.

Thanks, Aleksandar

I want to ask if there is some JavaScript libraries which is "black box", it recives SVG and/or JSON file which decribes line, circle, icon etc. and simply draw it on canvas?

None that I am aware of.
There are canvas commands, but they require the data to be given to them.
It does not automatically translated from any format to a specific display.
