excel Shapes and SmartArt

As I mention earlier in this chapter, each worksheet has an invisible drawing layer that holds
charts, pictures, controls (such as buttons and list boxes), and shapes.
Excel enables you to easily draw a wide variety of geometric shapes directly on your worksheet.
To access the Shape gallery, choose Insert➜Illustrations➜Shapes. The shapes are highly customizable, and you can even add text. You can also group objects into a single object, which is easier
to size or position.
A feature introduced in Office 2007 is SmartArt, which you use to create a wide variety of customizable diagrams. Figure 2-23 shows an example of a SmartArt diagram on a worksheet.
