Tutorial for Segments 034 – Cut 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 frameworks are different from the layered circles in sg022, each segment is a halo that surrounds the circle/halo within it. Each segment width is equidistant. There is no layering, so the colors stay true. This is another example of a seemingly simple framework that is time-consuming to draw.
The example to the right was discussed in the January 2007 feature article. Notice that the layering is used to illustrate primary and subsequent targets for rolling out a service offering.
Note: for another framework of concentric circles, see sg022.
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 has each halo colored a different shade of gray. If you want to use overlaid circles, download the frameworks in series sg022.
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. Maybe a zoom reveal, which builds from the center so it looks like each layer is building from the inside outward.
Another interesting reveal for this type of graphic is the wedge. The wedge reveals from the center top and ends at the center bottom.
