I realize this is serious necrobumping, but 2.0k views on the post and 206 clicks on the issue trackers, and then there is no link to a related issue, so here we go:
Is the relevant issue, I believe.
I think this is vital to use plotly sankeys for anything printable or non-html related, but even when used in a Jupyter notebook etc it does not present the relevant data without navigating the plot by hovering around.
Since there are not really many sankey tools around, there are actually no options for nicelooking+interactive+complete that I am aware of.
Plotly definitely ticks the first two boxes, but sankey is probably not the most sought-after feature.
I am grateful for what is there though. Keep up the great work.
