Feature Request: Sankey Node Default Order #2520
Description
I think it would be cool to be able to force an ordering on the nodes of a sankey diagram. I imagine the order in which nodes appear in the label list of a sankey data object would be a reasonable choice.

I would also highly value the ability to order the nodes in a sankey diagram.

@antoinerg I see you have assigned yourself to this issue, thank you for that! Since I have no JS-experience and cannot help out on the coding side is there anything I can do?

I agree, this would be very useful.
In my case, I have about 25 target nodes and plotly puts most of them in the correct order that I would like, but without fail it always has to put 2 of them in some random place, breaking the cleanliness of the plot. Manual ordering would help me fix this.
Also, in my case, the targets are unique to a source, meaning that there should never be a need for connections to overlap (which I suppose is a different issue, as whatever mechanism is used to auto-sort nodes really should be able to prevent overlap when it's not necessary).

Also, although we can drag nodes within a column, this isn't reflected in the state so on save/reload, export etc this info is lost. This position needs to be part of the state! Ordering should also work.
Thank you @jwilson8767 for the links!

Agree this would add value to the Sankey diagrams in Plotly. Without consistent node ordering the diagrams are not reliably reproducible.

The new feature
node.(x|y)sets the position of nodes in Sankey. Please follow this issue forsortingfeature.
