Creating alluvial diagrams in SAS

[Ubai]

Hi everyone,

I would like to make an alluvial diagram in SAS. I searched google and found only one link, which can be improved I guess. I though I can ask the experts. @WarrenKuhfeld, Sorry Sanjay I couldn't tag you here.

Here is the one link I found:

https://www.linkedin.com/pulse/alluvial-diagram-using-sas-ods-graphics-dmitry-shopin

I have also noticed that this diagram can be make using SAS Visual Analytics, but I don't have this unfortunately. 

I would like to create something like this, although I know it can not be an interactive graph in SAS:

Any help, ideas, codes please? I think this is a worth of a post in the Graphically Speaking Blog.

This is, I think, what is also called a Sankey Diagram - to be honest I don't like them as I fail to see how anyone can make any sense of the multitude of crossed lines but you might find this helpful from Github https://github.com/RhoInc/sas-sankeybarchart

I don't have anything to add beyond what has already been posted.  I know Shane Rosanbalm from Rho who wrote the code to which @ChrisBrooks referred you. Shane is an excellent ODS Graphics programmer, so I would follow his lead.

Actually, I think this is a way of making an important point - the "trends" in stacked bar charts over time are due to complex movements of individuals between categories, something which many people do not appreciate.

Thank you both. I'll use it.
