"People have always been fascinated by charts. The rationale behind
this fascination is hard to ascertain. Perhaps they represent a
manifestation of man's preoccupation with imposing order upon a
seemingly chaotic world. Or maybe they are simply one dimension of our
longtime infatuation with factual trivia. Still, the fact remains that
charts have meaning to a significant number of individuals in our
society"
