This article showed me that graphic design transcends professions, and is an art form that can be seen anywhere from a subway map to a powerpoint presentation. On a daily basis graphic design affects our lives especially as New Yorkers, from making your way to across town on the subway, to reading your favorite book, graphic design is relevant in many more ways than I originally thought. One does not have to be a professional artists to design or interpret graphics as anyone from a 5th grader to business executives have suffered through making a powerpoint at some point in their lives.
My question to the author would be, why not include some images of recognizable elements of graphic design to both grab the readers attention and to help them visualize the subject of graphic design? Which is a very visual art to begin with. A possible explanation is that the author thought it may distract the readers from the text to have images cluttering the page.
