    Hints:

    • You can change the appearance of the circle or curve by adding a shape fill, an effect, or changing the border.

    • If you want to create an advanced diagram such as overlapping circles, an organization chart, or a flowchart, you can create a SmartArt graphic instead of manually drawing each shape.

    • Circles and ovals are filled in automatically. If you don't want the shape to cover anything underneath, such as text or cells, select the shape and click the tab format on Filling effect, and then click no filling.
