Html5 canvas scrolling, zooming, fade out effect

Shahdat Hosain asked:

My final is goal to implement a app like http://www.crystal.ch/abb/power_systems_landscape/[^] using html5.

As you see, we may need a large(2000*600) canvas, but im not sure.

Can anyone give me idea just for following behavior of above link ?

1. Scrolling left-right smoothly using mousemove and mousedown operation
2. Scrolling left-right smoothly according to power system selection
3. Zoom in zoom out
4. Fade out effect like plus iconic circles

Any kind of idea would be appreciated.
