Liked your post and the idea of using Sankey diagrams to display website visits.

Although originally only for showing energy efficiency, Sankey diagrams today are used to display any kind of "flows": materials, energy, cash, cars, people, ...

I made two variations of your diagram on my blog: http://www.sankey-diagrams.com/using-sankey-diagrams-for-visualizing-web-site-performance/

BTW: I use a special Sankey diagram tool, so when changing the flow quantities (here: website visitor numbers) the magnitude of the flow will adapt automatically.
