Visualizing Multi Channel Funnels with D3

I thought it would be fun to amend this very cool D3 sunburst sequence demo for Multi-Channel Funnels in Google Analytics. This visualization shows the value (by number or value) of all conversion paths. The innermost ring is the first interaction and as you move out you can see the value of the path updating. The number of paths is capped at 5 to make it easier to see and the neat thing is that you can use the export csv file from the Top Conversion Paths report as is. All cleaning is done in the browser by D3 and some helper functions.
