Many of you have asked if I could name some software tools that can be used for drawing Sankey diagrams. So I am compiling a list of programs I have tested, or came across during my research. By no means do I wish to endorse any of these products, however, I do have a favorite, as some of the readers of this blog might have observed already.
I am grouping the list in (1) softwares that are specifically designed to make Sankey diagrams, (2) tools that support one specific type of Sankey or Sankey-style diagrams (this section also includes Matlab routines and open source), (3) software that are not available any more, and (4) other programs that do have Sankey as one of their features, but the main purpose for using the software is different. Time permitting I will do individual pages for the tools, and include my test notes and screenshots. The lists are sorted alphabetically.
This is a simple list. No warranty taken whatsoever for the software tools listed here. Download and install at your own risk. Contact the individual software makers for support, not me, please!
Please note: This list is to be understood as non-exhaustive! Do you know of any Sankey diagram software not listed here? Let me know
