PowerPoint are a rich source of good presentations. If you want to use a lot of graphics, sounds etc, then when a time for slide presentation comes, choose this program to conduct your slideshow presentation. In addition to photos and sounds you can add charts. There is actually a very easy way to do it:
1. Go to the slide where you want to insert a chart.
2. Go to Insert menu and select Chart option. A sample chart will appear for you on the slide. Now it is your job to modify it to suit your needs.
3. Remember to delete the data that you do not need and replace the data with the data that you want to present.
4. Click anywhere on the slide for changes to go into effect.
I believe that using charts is a great addition to text.
