Interactive Sunburst Chart selection: how to reproduce legacy node behavior with new Sunburst Cha...

Hello KNIME Community,

I have been using the Sunburst Chart (JavaScript) node in KNIME to create interactive sunburst charts. In particular, I built web app pages (e.g., in KNIME WebPortal) where after a user clicked or selected segments of the sunburst chart, the corresponding subset of data was dynamically shown in an associated table. This interactivity was really valuable for data exploration and dashboarding.

Recently, the Sunburst Chart (JavaScript) node became deprecated (i.e. a legacy node is still available) and replaced by the new Sunburst Chart node. However, I’ve noticed that the new node generates nice visualisations but does not seem to support clicking or selecting sunburst segments to filter or update other views downstream.

• Is there a recommended way or best practice in current KNIME versions to replicate the interactive behaviour where clicking on sunburst segments updates tables or filters data dynamically?

• Are there any built-in nodes, extensions, or demo workflows that showcase how to bind the sunburst chart segment selection to downstream filtering in dashboards or WebPortal components?

Thanks a lot in advance for your help! I’d appreciate pointers on how others have overcome this limitation.

Cheers,

Gio
