Graphic design is everywhere, touching everything we do, everything we see, everything we buy. Graphic design is the logo on your fizzy drink and the front page of The Times. It is the London Underground map, price tags in clothing stores, postage stamps and theatre posters. Graphic design is a complex combination of words and pictures, numbers and charts, photographs and illustrations that, in order to succeed, demands clear thinking so that all these elements can add up to something distinctive, or useful, or playful, or surprising, or subversive or somehow memorable.
