Hi Superset Devs, I am wondering if https://github.com/apache/incubator-superset/pull/7441 could be reviewed and tested to support loops in Sankey visualization. Our use case for Sankey viz would be displaying bytes flowing between BGP AS peers in our network datasets (not acyclic sadly). I am not sure what stopped the original pull request at the time, but I can surely help testing any code and report back to you :)
Thanks in advance, Luca
