d2b.chartSankey node click listener

[HJK181]

Hi @kevinwarne,

I'm having the requirement to drill down into the data of the Sankey chart when clicking on a node. Unfortunately, I didn't find any hint in the documentation so I wonder if this is possible at all?

Sry for using Github Issues for questions, but I don't know another way to get in contact with you.

Thx in advance.
