Hi all :),

When I'm starting to prototype a visualization I like to make all elements draggable so I can test easily several layouts. This works well for simple elements, but I can't understand well how to make it work with complex ones like the RTPieBuilder.

Consider the code at http://ws.stfx.eu/1HC0HALHUKIC . There I create a ring pie chart and visualize it. I would like to make it draggable and add more elements to a the view. I have browsed the layout chapter by Peter on Agile visualization[1], but still I don't get it. I will made a detailed reading to catch what I'm missing and redo some proposed exercises, but any help is greatly appreciated.
