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.
