דרוש פרילנסר מומחה לjave script

We need a javascript guru to create a cartesian math graph in html 5 with abilities to drag and zoom, dragging should be either infinite or until 10,000 in all axes (X axis is -10,000 until X axis is 10,000) and so forth.

On the initial zoom level, the square grid cells should be 48x48 pixels.

We require clean and clear and efficient code that will be easy to maintain.

Time is very important, we need it to be ready today.

Please review an example here: https://www.desmos.com/calculator
