Free sankey diagramm software freeware download software at UpdateStar - e!Sankey - a software tool to easily create Sankey diagrams. A Sankey diagram is a directional flow chart where the magnitude of the arrows is proportional to the quantity of flow.
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.
Free Sankey Diagram Software Mac Free
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

Sankey Diagram Software
Web-based, mostly building on open-source d3.js
- eco-data.fr (webpage)
eco-data.fr offers different types of online visualization tools, among which there is also a Sankey diagram. Based apparently on d3.js and the Sankey library the diagrams are built by defining nodes (‘noeuds’) and links (‘liens’). Dragging nodes horizontally or vertically keeps the arrows attached to the nodes. Your Sankey diagrams can be saved and reopened for modification. Enter values manually or loaded from a csv file. - Excel to Sankey (blog)

Sankey diagrams made with e!Sankey
Whether you are working in energy management, analyzing material streams in a production system, or your tasks revolve around supply chain, logistics and goods being shipped:
Sankey diagrams created with e!Sankey will really improve the way you are visualizing energy flows and mass flows.
We are providing new Sankey diagrams that we like and that are worth sharing. These files can be downloaded in the .sankey file format and opened in e!Sankey (version 4 or 5).
The original: energy efficiency of a steam engine
The first illustration of energy flows using arrows proportional to the quantity was created by the Irish engineer Captain Matthew Henry Phineas Riall Sankey. Even back then it includes many elements making Sankey diagrams so popular today.
We have recreate this diagram using our software e!Sankey. Just look how brilliant it was at that time.
By the way, you find a little insight into the history of Sankey diagrams just here.
Another retro style diagram

Many generations of students and professionals have been using the 'Dubbel - Handbook of Mechanical Engineering. It was first published back in 1914.
We have picked one classic black/white visualization of the 'Heat Flow in a Boiler' from Dubbel's book and have recreated it in e!Sankey. It can be downloaded here.
The original retro look has been maintained with heat losses shown with a diagonal hatched pattern just in the original figure.

U.S. energy consumption per capita
This Sankey diagram shows energy use per capita in the United States for the year 2006. More recent data is available, but the general picture hasn't changed: Huge energy losses occur in electricity generation and combustion engines of motor vehicles.
The diagram has been created with e!Sankey 4 and is based on data by Lawrence Livermore National Laboratory (LLNL).
You can download the .sankey file, and use it as a starting point for your own Sankey diagram.
Material & process flow diagram
Free Sankey Diagram Generator
Using e!Sankey you can also show different flows within one diagram, e.g. materials and energy. This is very helpful, when you would like to view production processes holistically.

The following diagram shows, how such a production process can be illustrated.
The advantage of this illustration catches the eye immediately: losses and energy are displayed separately from the material flow from left to right.
