Vizible Difference

Through my previous post on the new Sankey chart type, I got in touch with Wilson, the product manager leading the development of this new chart type. I made some comments on creating multi-level Sankey via cascading of single Sankey's. He told me it can be done already by dropping more dimensions into the Level card. How could I overlook that functionality when exploring? Maybe it's because there are only two level bars in the Level card icon? Or did I have a fixation on building multi-level Sankey via a Lego approach?

Oh well, I am really happy that we can build multi-level Sankey charts with a few drag and drops!

Below are a few varieties of multi-level Sankey chart built with the new chart type.

As an enthusiastic user of Sankey charts, I am excited to learn that a Sankey chart type is being piloted in Tableau Public (Web Edit only). I wrote about Sankey chart design in multiple posts. Sankey chart may appear in different forms depending on applications. 

I played a little with it just to evaluate it. Here are my initial findings and comments.

1. The basic Sankey

I can quickly create a Sankey with 2 dimensions and 1 measure.
