Sankey Diagram Software

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

Here is another list of Sankey software by Butler Analytics


  1. Magnus says:

    Hi Phineas, very informative and good overview of the Sankey art!

    Why not make a table with the different software and the features they have. This would be good information for the user who looks at different sankey softwares.

    I have some old sankey diagram from 1930’s if you are intersted. E-mail me!


  2. phineas says:

    Thanks Magnus!

    I am planning to extend this section on Sankey software tools, however, I haven’t yet decided on the best way to structure the grid to compare functionality of the tools. Also, for some softwares I don’t have demo versions, just information off the web, so I will have to contact the maker first. Please check back again later, to find out how far I have gotten…


  3. Chris says:

    Hi Phineas,

    very nice and informative blog about sankeys! Thx. Are you aware of any sankey software running unter Linux (Ubuntu)?



  4. phineas says:


    I am not aware of any Sankey diagram software running on Linux machines.


  5. daniel Alvarez says:

    i need sankey sofdware , ware can i find it.


  6. phineas says:

    @ Daniel Alvarez

    Daniel, there is a link to the website for each tool in the list above. You should be able to find information on acquiring a product on the respective maker’s website.

    Daniel, en la lista de programas arriba tienes los enlaces para los sitios web. Ahí puedes encontrar información como obtener las programas Sankey.

  7. BeGraphic says:

    We designed BeGraphic which is a data visualization tool inside Excel and PowerPoint made to present new graphs,business charts, choropleth maps, dynamic diagrams… including Sankey.

    Any Sankey diagram can be easily done by using only three functions: “Resize”, “color” and “Magnet”. The all diagram is dynamically animated based on Excel cells’ values.

    If you want to test BeGraphic software, just let us know.
    Best regards,

  8. Kyle says:

    I tried the Excel plug-in Sankey helper and found it seems to have brought Excel down – it will now only open in safe mode. So the first comment is a warning, especially for people like me that depend on Excel every day. Then a question – has this happened before and how do you undo things like it?

  9. phineas says:

    @Kyle: you should contact the maker of the software. This list of Sankey diagram software is not a support forum.

  10. GlenT says:

    Wow, thanks for the great list here. I was searching for such a list for quite a long time. I am interested in sankey diagrams for few weeks now, so I want to find the best software for this hobby. I will read your review one more time and decide what applications to download. Thank you one more time, and I will be waiting for another great posts from you.


    Glen Thompson from software development company

  11. Brian says:

    The message from “begraphic” appears to be misleading spam, Their graphics software offers lots of options to display graphs, but I couldnt find any mention of sankey diagrams on their website, even a google search “sankey” didnt yield anything.

  12. r says:

    For linux users, openoffice draw can be used. See the user forum

  13. The RSS feed doesn’t work with the internet browser (opera browser) how to deal with it?

  14. Sami says:

    Brian, I found this from Begraphic website. It says that Sankey diagrams are available in Pro version, due to launch Jan 2011.

  15. Antonio Bardazzi says:

    Proof of concept Ruby Sankey library based on RMagick. Create a simple image without labels, colors or other graphic like this:

    Can represent multiple process with multiple independent flow forcing mass conservation (input size must be equal to output size).

    Each flow can be consumed by a process (the process drain the flow), produced (the process is the source for the flow) or both.

    This example represent the diagram for making coffee:

    The first process is a grinder that drains beans and output ground coffee. The second process is an espresso machine that drains water and ground coffee and output coffee and cream.

  16. thanks for sharing a good information.

  17. Thanks for the list of software tools that can be used to draw Sankey diagrams!

  18. Thanks for the list of applications that have some kind of Sankey functionality. Very helpful.

  19. Hi

    very nice tools………

  20. Gabor says:

    I was alerted to the comments of Kyle and Trent a few years back, reporting problems with Excel after using my SankeyHelper. SankeyHelper is *not* a plug-in, but merely an Excel workbook. It contains however VBA macro routines to help you create Sankey Diagrams. Some Windows anti-virus software or Windows Operating system get into a paranoid panic upon seeing a file with VBA, although it is a perfectly standard content and part of the MSOffice Suite (see The apparent reason for this is that VBA is powerful and can be used to produce malware. *Please* consult your anti-virus software and Windows manuals to learn how to set safety features and security features of your system in order to avoid unpleasant surprises with VBA. Mac users have no such worries. Btw. SankeyHelper has no digital signature, as Mac users are exempted by design from creating them (*glare*). So you need to *enable all macro execution* on your Windows computer to use SankeyHelper.

  21. Joao says:

    Like some previous users, I tried Sankey Helper 2.4 and it corrupted my Excel. It only starts in safe mode now, even after reinstalling in several ways, restoring the system to a previous date, etc. I have Windows 7 with Office 2010.

  22. Joao says:

    Here is a procedure to fix Excel 2010 after Sankey Helper 2.4 corrupts it (I have windows 7):

    1. Uninstall Office 2010 and reboot.
    2. Manually delete any folder named Office or Excel under C:\Program Files or C:\Users. Note that you first need to select “see hidden files and folders” in the file explorer (tools\folder options\view).
    3. Install a clean copy of Office 2010.
    4. Go to Control Panel, Programs, Programs and Features. Select Microsoft Office and choose “Repair”.

    This solved my problem. Good luck.

  23. Colm O'G says:

    There is a javascript library I stumbled across in github

    The example given is nice, not perfect, but a good start, I would say it needs work on the corner definition

  24. I used some of them and they are really great. Thanks for sharing this great post.

  25. tom says:

    your blog is very informative. am a student in Kenya and i have not used any of the sankey software before. my research is on petroleum flows in the country as well as associated GHG emissions from 5 major sectors of the economy. which software would you recommend?

  26. phineas says:

    @tom: Everybody has different criteria for choosing software. For some it is the set of features, for others the operating system the software runs on. And, most certainly, the cost of a license (freeware vs. commercial software) plays a role.

    Why not download a trial version of the software tools listed in the first section (“Full Sankey Software Tools”) and test it to see, if it suits your needs and requirements.

  27. Here’s an example of creating sankey diagrams straight out of excel, integrating with d3.js and its interactive sankey plugin. Its not an excel plug-in, just some VBA code you can use which generates a standalone web page.
