Charts can help viewers of your presentation better understand quantitative information without overwhelming them with an avalanche of numbers. Using a chart, you can present complex data that can be understood at a glance. Charts illustrate the relationships between different sets of data, and they are also good for showing trends over time.
PowerPoint provides you with a wide variety of chart types, and you can manipulate those charts in many different ways to get your point across. You should have no problems tailoring charts to suit your taste and the needs of your presentation.
You can also animate the parts of a chart to have them appear on your slide one at a time. To create these chart builds, see Chapter 10.
