charts and infographics, has just launched a new section called “The Chart Doctor”. Its first article discusses the widespread and wrongheaded idea that any visualization should be understood in just five seconds —if possible, yes, sure; but it's rarely possible.
A few days ago I wrote against that idea: Simplicity is a virtue in visualization, but complexity isn't a vice when a complex graphic is necessary to tell a complex story with adequate depth. As the old saying goes, everything should be made as simple as possible, but not simpler.
As I wrote in The Truthful Art, quoting Nigel Holmes, the goal of information graphics shouldn't be simplification, but clarification, which is similar to what John Maeda's classic book calls simplicity. Clarification often involves increasing the amount of information shown, not reducing it mindlessly. And when an unusual graphic form may be much more enlightening than a traditional one, we ought to give it a try, not just take refugee in the self-defeating and lazy “our reader won't understand this.”
