Sankey: Visualizing paths through a column/node

[Vaughn Shirey]

Hi all,

I've been working with Sankey for awhile now, but noticed that there is no way to highlight a path from Point A to Point Z where it intersects multiple nodes in between. A particular case I've outlined below:

Year -> Book Genre -> Authorship

I want to be able to visualize when clicking a year, the genres written (already able to do this), but also the authors within those genres. Any tips? I'm working within a Shiny framework.

Thanks!
