   I would also love seeing drill down/through functionality added to Superset! I think there are roughly two ways forward here:
   1) adding drill down in the chart layer, much like has been done in #14688
   2) adding support for hierarchical dimensions to the semantic layer.
   
   Both probably have their pros/cons:
   - Adding drill down to a single chart is fairly straight forward and wouldn't require a lot of changes to the rest of the application. On the downside it's slightly hacky and might introduce some design debt.
   - Adding semantics for defining hierarchical dimensions would make it possible to introduce drill downs into any chart (including native filters), but on the downside it's a fair bit of work and could take long to implement.
   
   As we're getting ready to kick off work for Superset 2.0, I'd personally vote for the second option, as I feel having full drill down support would be a very valuable (and cool!) feature.
   
   @betodealmeida , has any consideration been given to adding hierarchical dimension semantics to the new dataset models?
