I found Jeff Shaffer's blog post

<http://www.dataplusscience.com/SankeyinTableau82.html> on using Tableau to

create Sankey Diagrams quite helpful. I would like to build a similar

diagram in Tableau, but I do not want to compare rank at one point in time

to rank of the same dimension at another point in time. Rather, I'd like to

show partnerships between schools (one dimension) and arts organizations

(another dimension). I created such a diagram using raw.densitydesign.org (see

below) but it will only creates static visualizations and does not allow

for filtering or highlighting.

The problem with using Shaffer's method seems to be the calculation for the

curve which relies on numeric values (position and position 2). Any

suggestions would be greatly appreciated!
