Using Graphics as Persuasive Elements
Graphics are fundamentally important in communicating persuasively because they help you convey both technical data and nontechnical information. Figure 8.5, for example, shows how a combination of verbal and visual techniques can make a persuasive argument.
Photographs can be used to convey technical evidence, as shown in Figure 8.6.

Figure 8.6 A PHOTOGRAPH USED TO PROVIDE TECHNICAL INFORMATION
Images of the same scene at different times can provide technical information about changes in a physical environment. On the left is a photo of Northwestern Glacier, in Alaska, in 1940; on the right is the same scene in 2005.
