There are some great resources on the Web for creating visuals. This page, put together by some folks at Illinois State, offers some general principles for creating graphics, some explanations of the graphic types and how they should be used, and also gives some examples of bad visual design. The page lists a point from Strunk & White that really captures one of the main ideas I hope everyone comes away with in this class:
"A sentence should contain no unnecessary words, a paragraph no unnecessary sentences for the same reason that a drawing should contain no unnecessary lines and a machine no unnecessary parts."It's easy to scan this for valuable information and well worth a look. It even includes tips for anyone who plans to use Excel to create visuals, something that will certainly be useful for some of you on the research report assignment.
