Seeking a flexible image plugin with pan and zoom

I have been searching through the plugin directory and am coming up empty handed.

I have a site where just about every post (some links below) include stock charts. Those charts are fairly large and I would love to include the ability to zoom out or pan around the image. Has anyone come across such a plugin??

FWIW users are complaining that they cannot fit the entire chart on their screen. I don’t think a smaller image is the answer as it will become unreadable, hence my desire to pan and/or zoom.
