Supply one data set where:

• The first three values specify the relative sizes of three circles: A, B, and C.
• The fourth value specifies the area of A intersecting B.

Description:

• In this example, the value 100 specifies the first circle, the value 80 specifies the second circle, and the value 60 specifies the third circle. The values 30, 25 and 20 specify the areas of overlap between each pair of circles. The value 10 specifies the area of overlap between all three circles.For information on available parameters for Venn diagrams, see Optional parameters by chart type.
