Good afternoon!

I created some Sankeys to better visualize certain relationships and they mostly work well. Following the example provided here: [Sankey Creation](https://www.elastic.co/blog/sankey-visualization-with-vega-in-kibana) resulting in clean graphs but with a slight issue.

The data corresponding to left and right sides of the sankey have no matching names at all. (Think mailing type and country, ie, Left side is: express, letter, package and the right side is: Canada, UK, USA)

So while the left side looks perfect, the right side does not contain the solid block for each category name, which does not enable a reverse match mouse hover over.

Does anyone know what I need to add to ensure this visual and feature occurs bidirectionally and not just Left to Right?

Additionally, has anyone had any luck with creating a multiple part Sankey? (3 or more pieces, such as Sending Country \> Mail Type \> Destination Country)

Heya! Thanks for the response.

No, I have yet to find a solution for the sankey issue.

Can you provide me with an example/simplified version of your ES documents and the vega specs you are using? I can check if I can make it work for you
