Interactive filtering histogram widget with cartoJS

I would like an interactive filtering histogram widget like this one https://public.carto.com/builder/0c982e6d-b254-4e2b-86ed-e0f097f519c2/embed (the population density histogram widgets on right bottom of screen). When you click or select histogram’s bars data are filtered on map.

I know how to do this with cartoDB;
https://carto.com/help/tutorials/improve-the-message-of-your-map-through-styling/#leverage-autostyling
What I want is to make 1 with cartoJS.

As cartoJS solution, I found this histogram widget : https://carto.com/developers/carto-vl/examples/#example-viewport-histogram-widget
but the widget is not interactive.
Clicking on histogram’s bars does not filter the spots on the map.

Does anyone know how I could make an interactive filtering histogram widget with cartoJS ?

I built this coloured Airship Histogram widget : http://softpeople.fr/DEMO/cartoDB2/4.html

This time I made Histogram coloured but still I can’t find a way to apply filtering on datas map by selected histogram’s bars.

Is this even possible ?
