When using SmartArt PowerPoint lets you communicate information with graphics. Use PowerPoint SmartArt to illustrate specific ideas.
After inserting SmartArt, there are several things you might want to change about its appearance. Whenever you select a SmartArt graphic, the Design and Format tabs will appear on the right side of the Ribbon. From there, it's easy to edit the style and layout of a SmartArt graphic.
If you don't like the way your information is organized within a SmartArt graphic, you can always change its layout to better fit your content.
If the new layout is too different from the original, some of your text may not appear. Before deciding on a new layout, check carefully to make sure no important information will be lost.
