How to implement the jquery plugin “Circliful” in a chrome extension?

I am making a chrome extension and I would like have some circular pie charts like those from the jQuery plugin circliful. The charts show up fine when I link my popup.html document to circliful’s scripts and open the popup as a window in Chrome, but when I try to open the same popup.html page as a packed chrome extension, the charts don’t show up.

Do I need to declare special permissions in the manifest file? Is there another way to make this plugin work for my chrome extension?

Thanks very much in advance!
