I agree with this poster - the power bi default visuals are currently lacking the ability to break on facets and grouping those on other dimensions.
I think the only think holding this visual back is that it is poorly marketed and I don't see anyone in the powerbi community playing with it in there videos.. (guy in a cube, curbal, pragmaticworks)
Do they know it exists? - Have demonstration videos been pushed out to them - have sessions been scheduled to demonstrate the visual analytic capability?
