An infographic (information graphic) is a representation of information in a graphic format designed to make the data easily understandable at a glance. People use infographics to quickly communicate a message, to simplify the presentation of large amounts of data, to see data patterns and relationships, and to monitor changes in variables over time. Infographics abound in almost any public environment -- traffic signs, subway maps, tag clouds, musical scores and weather charts are just a few examples, among a huge number of possibilities. They predate writing as a means of disseminating information -- cave drawings are probably the earliest known example. People were also creating and using maps before the advent of written language. These are some of our most recent infographics.
