> Any sufficiently complex problem requires looking at it from different angles in order to root out the unexpected and ambiguous. Visualizations do exactly that. To me, this is an underappreciated tenet of good visualization design. Bad/lazy visualizations show you what you already know, in prettier form. Good visualizations give you a better understanding of things-you-don't-know at the time of designing the visualization. I.e. If I create a visualization using these rules, will I learn some new facts about the "other stuff"?
