dynamic navigation image

[dino d.]

Hi- I'm trying to build a dynamic navigation map, like google
maps,except the map will be a graphical representation of some data.
When the user drags the map to the left, the script should generate a
new part on the right, and vice versa. I'd also like the ability to
zoom by scroll wheel. Can anyone point me to some sample code to get
me started?

Thanks,
Dino
