I am using Raphael to create lines between divisions in an organization chart (or flow chart), but I need to be able to actually click on the divisions and content behind it.

If I could make the canvas be behind the other elements, kind of like a background image, that would be idea. Is this possible?

UPDATE:

I found a solution. Raphael makes an SVG canvas that is absolutely positioned in my case. Absolute positions act as layers, and so to be on top of that layer, my content had to be absolutely positioned as well.

If someone else has a better solution, I would be happy to hear it, though this is working fine.
