I want to create a chart that can be clicked in certain regions of the bars or line. Is this possible?

Is it possible to make portions of a Dojo Chart clickable? For instance, I'm making a bar graph, and I'd like each of the bars to link to a detail page.

As a background, I'm currently trying to decide between JFree and Dojo for a charting solution. I would love to use Dojo, but I can't find a way to generate imagemap-esque link and hover info for the charts. I looked through the available examples but couldn't find anything.
