Chapter 7.

Chapter 7 put a great emphasis on visuals.  It breifly talked about tables, graphs and charts. it explained the basic funtions that they served, and why they were important. the section on icons and symbols caught my attention. When creating an icon or symbol, you must account for your audience. Symbols and icons are important for large populations that may not speak one universal language. For example, a symbol of a skull-and-crossbones image means "danger" or "warning". This is something people from most cultures will understand right away. It is helpful, becuase there gemerally aren't any language barriers associated with these items.
