Download Onion diagrams and PowerPoint templates with concentric circles and shapes that you can use to represent a hierarchy of elements or relationship of concepts.
Concentric circle can be defined, in geometry, as two or more objects that have the same center or axis but different sizes.
You can easily create concentric circles in PowerPoint by creating a circle, and then duplicating it several times. Then, reduce the size of some of the duplicated circles and align all them centered together (vertically and horizontally).
Instead of re-creating the concentric circles by hand and reinventing the wheel, you can use a concentric circles template for PowerPoint. In our catalog you can find thousands of concentric circle templates for PowerPoint and Google Slides.
