> correlated drill down could you elaborate on this?

  Say you have a map and a barchart in two different figures. If I select a province or state in the map, with correlated drill down the barchart also updates.

    And this type of thing is why companies end up with Tableau. The open source projects are catching up though. Is this on the roadmap for Superset?

    Even more advanced is brushing & linking, where you reproject a selection in one chart into another (assuming they are slicing along different dimensions - https://imgur.com/a/70ngkn3 https://imgur.com/a/70ngkn3). I haven't seen too many open source products that can handle that (and not too many commercial BI products either).

      Precisely. Altair/Vega-lite are good examples of projects that do this well (but its all client-side rendering so YMMV).

        Yeah, it would be quite easy to do it with SQL based BI tools, as long as you can invert the selection back into a where clause. The tricky bit is overlaying the new data on top of the old (especially when you completely filter out some subset of the data, like a few bars from a barchart).
