You see information graphics at least once every day, an information graphic is a pices of graphic design that can give the viewer information on ceratain things, for example a map of a building or school is an information graphic as they can tell you where you are and the other areas of the building, most information graphics use icon/symbols that are easy to understand as it is a quicker way of getting information to the target audience, posters, leaflets and brochures are also information graphics.
