Abstract:

One of the nice things about technical writing courses is that most of the papers have graphics in them — or at least they should. A lot of professional, technical writing contains graphics — drawings, diagrams, photographs, illustrations of all sorts, tables, pie charts, bar charts, line graphs, flow charts, and so on. Once you get the hang of putting graphics like these into your writing, you should consider yourself obligated to use graphics whenever the situation naturally would call for them. Unlike what you might fear, producing graphics is not such a terrible task — in fact, it can be fun. You don't have to be a professional graphics artist or technical draftsperson to produce graphics for your technical writing. There are ways to produce professional-looking graphics with tape, scissors, white-out, and a decent photocopying machine.
