This series can be used to show relationships and segments or, as in the example, even timing. This series is drawn so that it appears 3D. We left colors in the EMF and the PowerPoint downloads to give you a guide of how to apply colors from your template. There are "lighted" segments and "shaded" segments. Do not apply 3D to these frameworks, use the shading.
Refer to the tutorial for more specific information on formatting and download the animated example for a possible animation scheme.
