Hmm - I hadn't thought about the dashboard / data viz creation side of this. Not sure that I'd want to be sitting in my cube creating dashboards "out loud".

"Okay, let's bring in 'Sales' to the rows card.

"Nah, I don't like that. Move 'Sales' to the columns card.

"Hmm, that doesn't work either. Put 'Sales' back to the rows card but add 'Profitability Indicator" to the details section.

"Crap. Still not working. Let's start over."

Imagine 10 analysts in a room all talking like this :)
