Hey marcint! I have to respectfully disagree. Data is as much a part of the design as the design itself (arguably more important), and if you can’t sell a design to your stakeholders, then you’re dead before you even started.
A beautiful wine label might sell a shopper, but the bottle will never be finished if the wine sucks. It’s monumentally important to give data a lot of thought as you’re crafting the experience for your users.
