What's the Constraint of a Data Visualization Project?

There's always a base somewhere of like what data are they going to use? You know, where is it going to be published? So there's all this analysis phase. And then I guess it's a bit of a mix match. The only added thing that I do and then pentagram does too is what we call creative direction,. We're trying to find what makes those data violations stand out. How do we connect them to the like the voice of the brand?
