I have a question, that is closely related to this one.
As opposed to the example, I also need to transition the innerRadius of the sunburst, hence the innerRadius property of the d3.svg.arc(). I know it has to be done in a similar fashion with respect to the transition of the "d" (with attrTween by storing the old innerRadius) but I didn't managed to do it.
Any suggestion? A code snippet would be great!
