Traceable multi-level Sankey chart

[noratolgyesi]

There is already a Sankey custom visual. We can even create multi-level Sankey. We can click on any node/level to highlight path. However, it has its limits.

We would like to be able to click on any path itself to highlight the route of the data in the whole chart. (Think of Google Analytics' behaviour flow chart). Currently, that is not possible.
