Graphic Design

For the graphic design lecture i was away, however looking though the presentation notes on blackboard i can get a real understanding of all the different sides to graphic design. As my chosen pathway I've never really thought what is graphic design? Now looking thought some of the images posted i see a pattern of logos, layout and typography shown. I love working with text and layout and i think if everyone looked at examples of these it would give people a good understanding of what a good layout looks like depending on the style/subject it for.
