When you need to clearly illustrate a concept such as a process, cycle, hierarchy, or relationship, you can create a dynamic, visually appealing diagram by using SmartArt diagrams. SmartArt is almost certainly the coolest new feature available in Word 2008 for Mac, Excel 2008 for Mac, and PowerPoint 2008 for Mac.
To avoid confusion, in this book we refer to graphics created with the SmartArt engine as diagrams. In the program interface, you’ll see references to SmartArt graphics. Both terms refer to the same thing.
From the extensive library of SmartArt layouts, you can create simple diagrams depicting simple concepts, or very complex graphics that earn their reputation as being "worth 1000 words."
