[jQuery] fastest way to create a million div's?

I am trying to create something like ms paint in jquery and I want it
to support 1000X1000 and that's a lot of pixels(one million to be
exact).

each pixel is a div so I need a way for handling that much divids.

I currently map an array as an image and then create an element for
each pixel.

but it takes a lot of time and in an image of 500X500.

please help.
