Can you suggest any jquery plugin/HOW-TO to implement minimap componentt?

Hi,<p>I am using jsPlumb for creating a process diagram editor and I am looking to implement minimap feature which is something like this https://dl.dropbox.com/u/107176/example-shot1.png. Can you suggest HOW-TO or what plugin to use ? Also I am not using canvas, instead its jquery+SVG+css as jsPlumb defines. Any help would be great, thanks.
