Plotly Sankey with a reverse flow produces a blank diagram

[jcallan]

I created a Plotly Sankey chart with forward flows easy enough but when I try to create a backward flow the chart produces a blank screen! In a forward flow the source is less than the target. When I make the target less than the source a blank chart appears! Is it possible to do a backward flow in a Plotly Sankey chart?

Thank you @jcallan for reporting this issue. It most certainly comes from the plotly.js library and we’re tracking the issue over there: https://github.com/plotly/plotly.js/issues/3813 . A fix should be available in the next release of plotly.js.
