Layered Concentric Circles
Using Concentric Circles
This series shows radiation from the center, boundaries around the center, core and layers around the core (onion effect), and other concepts illustrated by a concentric circle structure. These are layered circles on top of each other, each layered circle is equidistant. They are layered circles so that shading and 3D effects can be applied. This is another example of a seemingly simple framework that is time-consuming to draw.
Customizing Concentric Circles
If you want to change the size/shape of the PowerFramework, be sure to group it and resize the entire group. Once resized, ungroup to proceed with other customizations.
Select color from your document's color palette or a complimentary color so that the PowerFramework will reflect the color scheme of the rest of your document. Do not eliminate the lines unless the pieces are different colors.
The above example uses transparency to tell the story. All of the circles were colored gray and made 70% transparent. The different shades of gray are due to layering; the top piece is picking up some of the color from the layers below it, and so forth. This is a good method to show something radiating from center. Eliminate the lines if you format as transparencies.
Use a very short 3D depth for this framework or it will look like a sideways wedding cake.
Be conservative with shadows. Because of the layering, the shadows from the pieces in the front can obscure the bottom pieces if the shadows are too long. If you want the framework to look like on object, only apply a shadow to the largest, outside circle. If you want it to appear as individual layered objects, apply shadows to all of the circles.
Gradients, patterns, and pictures
Gradients can be used to create a distinction between the pieces. The lines can then be eliminated.
Animations should be selected that will enhance the meaning of the message, not merely to add interest to the slide. Simple reveals are best with this type of framework.
Another interesting reveal for this type of graphic is the wedge. The wedge reveals from the center top and ends at the center bottom.
