A picture is worth a thousand words. But when that picture is itself made of words, your mileage may vary. Take the case of type-based infographics. Bad use of type clutters an image; it acts as decoration – yet becomes a roadblock to information transfer. However, good use of type can add an extra layer of data to a graphic. Text and type within an infographic can be used to place high-density packets of information within a larger context.
