Large Flow Chart Process Graphic
I'm looking for ideas. I have a couple of screens in an e-learning course that include a large complicated flow-chart process graphic. I need to make the steps clickable so that people can learn more about each of them. I cannot change the graphic as it is a federal government approved image/process and they are very tied to the look and feel. Unfortunately I cannot post the image, but I've posted a blacked-out diagram to give you the idea.
I've considered something with zooming, and also considered trying to figure out some sort of scrolling process without the scroll bar being so visible. Any ideas would be greatly appreciated.
