Possible to hide specific nodes in plotly Sankey diagram?
For any nodes that you want to be "left-aligned" (i.e. end before reaching the farthest left of the page)....
Give these nodes a path to the most "right-aligned" terminal node, but set the color of the path to fully transparent #00000000. This should do the trick.
My objective is to produce a Sankey diagram in plotly (in Python) that does not have all terminal nodes justified on the right. My data is such that certain flows have only one or two intermediate nodes and others have many intermediate nodes. I would like for short flows to be highlighted by visibly terminating before reaching the right edge of the graph. As far as I can tell, there is not currently a way to do this. 
However, I thought that a workaround might be to just include dummy nodes and links in my data as needed and either set their visibility to False or make them completely transparent. But so far I have only found visibility and transparency/opacity approaches that apply to the entire graph.
So, is there any way to do any of the following:

left-justify a Sankey diagram (best option)
change visibility of individual nodes/links (good enough)
change transparency of individual nodes/links (also good enough)
