Hey dude, cool infograph

Edward Tufte, a leading authority on the display of quantitative information, is very explicit in stating that any graphic elements not in support of content are superfluous. "chart junk" is the term used to describe excessive attention to aesthetics over clearly representing meaningful visual associations between data.

That doesn't leave much room for distinct personal flair. Do you believe, as Tufte does, that "best practice" should be strictly adhered to when it comes to displaying information, or is there some room for more expressive form?
