> You're ignoring the reason data visualizations exist in the first place.
My opinion on pie-charts and poor visualization comes from years of studying data visualization, not ignoring it. Would you argue that Tufte doesn't value data visualization since he holds the same views?
Tufte can back up what he says with reason and examples, rather than repeatedly making the same assertion. Just saying "well Tufte says so" is a pretty blatant appeal to authority.
