Joe sent in this request earlier today:

I’d love some feedback on a viz that was just posted here:

My challenge is to visually communicate a data set (available in csv format here) with a lot of possible combinations (12 ETFs, 102 countries, 101 allocations). I’m using a Sankey diagram to show the relative sizes of constituent parts and links and users can drag a slider to change allocation. There exists a lot of of extra data in the hovers.
