In the past, you could type a number to set the spacing between each Node in a column, but:
Getting the spacing just right involved a lot of trial and error.
If you changed your diagram’s height or margins, the spacing value was not adjusted accordingly.
Now, you have a ‘Spacing’ slider which gives you an easy way to try out many different spacing approaches without needing to guess at a specific number.
And as a bonus, the look of your diagram will be preserved even when you change the height or margins.

One thing to keep in mind: The more spacing you add, the harder it becomes to accurately compare flow sizes, as you can see above.
Try it out! It’s actually pretty fun to experiment with.
(Honestly, it’s one of my favorite features ever.)
More fixes
Color themes were not being applied to Nodes when their names used non-Latin characters. This now works as expected. Thanks to @IvanaGyro for the bug report.
Now, choosing a color theme for your Nodes is much more flexible and fun.
There are now four updated themes to choose from (up from 3). For more about these color schemes, visit the d3 color scales page.
Each theme’s colors are visible at all times.
You can now rotate the colors within a theme so that SankeyMATIC will start assigning colors from any point in the list that you choose.Click the “<” and “>” buttons for your selected theme to adjust the starting point.
Every color in every theme will reveal its color code when you hover over it.This is handy if you want to adopt one specific color in your inputs.
SankeyMATIC now uses version 7.3.0 of the d3.js library (a major upgrade from version 2.10.3)
Labels for selected radio buttons and checkboxes are now highlighted with color to make them easier to find.Labels for un-selected radio buttons and checkboxes are now dark gray instead of black.
SankeyMATIC has long had the ability to adjust the curvature of flows with a slider labeled Curviness.
However, it has not had the ability to remove all bends from the flows, since that actually requires a different drawing approach. (Straight or flat flows are really parallelograms, and no Bezier curve is going to produce that shape.)
That problem is now solved.
Setting the Curviness slider all the way to the left now produces truly straight flows.
Still a little curved…
Totally flat!
New Feature: Extra Large image download format: 6x
For people who want higher-resolution output, there is now a 6x PNG image export option.
Tip: Depending on your diagram size and on your device, generating 4x or 6x images may make your experience filled with long pauses.To avoid this, set the export PNG image’s Size to 1x or 2x while you are setting up your diagram so that you can iterate quickly.Wait until you are truly ready to export before choosing 6x.

and so on.
Better filenames for downloaded images
Downloaded PNG image files now have a date/time stamp in the name, like: sankeymatic_20220130_155723_600x400.png.
This makes it easy to sort the files by when you created them, which is often handy.
This also avoids annoying duplicated filenames – you won’t see “sankeymatic_1200x1200-3.png”, “sankeymatic_1200x1200-4.png”, etc. any more.
Added “Made with SankeyMATIC” tag
When people post their SankeyMATIC diagrams to social media, it’s very common for others to ask: “What did you use to make that?”
I’ve added a Made with SankeyMATIC tag to diagrams by default to help answer the question before people ask it.
For anyone who does not want the “Made with SankeyMATIC” tag, there is a simple nearby checkbox, plainly visible, to remove it.
Other minor changes
Various improvements to the SVG code which SankeyMATIC produces – better organized, better labeled, no unnecessary precision, etc.
Fixed a bug where unwanted trailing 0s could appear on values when the chosen Number Format used a ‘,’ as the decimal point and ‘Always show full precision’ was unchecked.
Updated the JavaScript dependency Canvg to version 3.0.9 (from version 1.3).
Appearance controls which use sliders (examples: Curviness, Node Opacity, Flow Opacity, Border Width) now make immediate changes to the diagram as you drag them.
This makes it much easier to observe what each slider is doing and to precisely pick the value you want.
Added multiple sample diagrams
Now there are 3 different diagrams you can use as starting points when you first begin.
Note: When you have made any changes to the Inputs field, choosing a new base diagram will alert you that you will lose your changes if you continue.
Other minor changes
In the Inputs section, comments are now indicated using two slashes (“//”) instead of an apostrophe.
The double slash is a standard comment marker for many languages and formats, so this will hopefully be more familiar to more people.
Typing apostrophes on iOS devices defaulted to the ‘smart’ version, making it require several steps to successfully enter a comment. This change eliminates that difficulty.
