Using SmartArt in Word documents lets you communicate with graphics in Word documents instead of only using text.
SmartArt allows you to communicate information with graphics instead of just using text. There are a variety of styles to choose from, which you can use to illustrate many different types of ideas.
You can also add text by clicking on the desired shape and then typing. This works well if you only need to add text to a few shapes. However, for more complex SmartArt graphics, working in the task pane is often faster.
