vega-lite-v5 get selection

I would really appreciate some exemples on how to display a filtered table (like printTables) from a vega lite brush selection.

Another exemple with an external map made with Leaflet. How to get the selection from vega-lite-v5 charts and filter items displayed on the map. Bijective direction would be nice as well : items displayed on the slippy maps are the only ones displayed in the vega-lite-v5 charts

Exemples with such features with cars.json are crudely missing.

I’ve prepared a small notebook featuring filtered plots built with vega-lite-api v5.

I have a few open questions:

  • How can I retrieve values from Vega-Lite brush selections, use them to filter data, and display the results in a printTable, in a Leaflet map ?
  • How can I highlight the current markPoint with a stroke on mouse hover (in addition to displaying the tooltip)?
  • Is there a way to implement same cross-filterings using the Plot library rather than vega-lite-api ?

Any insights would be greatly appreciated.

I have found a solution by using @john-guerra/vega-selected.

Here is the original notebook: Brush / Patrick Brockmann | Observable
and a solution: Brush / Patrick Brockmann | Observable

Is there an official version from the Vega project itself by UW IDL ?
