The point of an infographic is to use visual cues to convey information more clearly and readily than would be possible using text alone. Great infographics can be absurdly simple or dizzyingly complex, so long as they’re intelligible and coherent.
The Internet has democratized many things, for better and for worse. So far, the democratization of infographics has been for worse.
Many are utterly pointless, amounting to little more than a bunch of bullet points dressed up with ugly colors. Others are simply inane, applying bar charts and pie charts seemingly at random to answer questions that no one was asking in the first place.
Still others are so bewildering as to make one yearn for a good old block of text instead. But to me, the most galling of all are those that imply some sort of relationship or equivalence between a bunch of numbers that have almost nothing to do with one another.
In many cases, they leave you with a poorer understanding of the topic at hand than you possessed before you read them.
