Using the Webs
Webs can be used to illustrate networks other than the WWW. This series contains a few options for you: webs with 6 to 12 lines from the center, with either 2 or three circular connections. This should give you all the options you need to present simple networks. If you want to get complicated, however, you can connect several webs to make connected networks on a slide. These would be used to give a macroview instead of a microview of a network.
Once you have identified the best-suited PowerFramework, download it to a specific location on your computer so you'll be able to find it (the desktop is always a good choice).
Customizing the Webs
Group the web and resize it or rescale it (hold shift key down as you resize).
Apply a line color from your template's palette or apply a complementary line color.
Don't use 3D.
Don't use shadows.
Gradients, patterns, and pictures
Don't use gradients in the lines (PowerPoint 2007 only).
Animate as reveals or with motion paths, as in the downloadable animation example.
