What is a Venn Diagram ?

A Venn diagram is a series of circles that overlap one another.

Venn diagrams are commonly used in mathematics to illustrate how sets and subsets intersect.

In PowerPoint 2003 the colours blend automatically based on the colours applied to each circle.

You can make manual adjustments to the colours by adjusting the transparency on the (Format > AutoShape) dialog box.

Creating a Venn Diagram

Insert a blank slide and select (Insert > Diagram).

Select Venn diagram from the Diagram Gallery dialog box and press OK

Inserting Shapes

The Diagrams toolbar is automatically displayed whenever a diagram is selected.

The first button on this toolbar is "Insert Shape" which can be used to insert more circles to your Venn diagram.

When inserting new shapes you should select an existing shape which you want the new shape inserted next to.

 Move Shape Backward - Only available when AutoLayout is switched on.

 Move Shape Forward - Only available when AutoLayout is switched on.

Things to Remember

In PowerPoint 2002 and before the colours did not blend particularly well.
