you can insert>smart art >illustrations in Excel to get a Venn diagram. Your data would then be in the circle textboxes.
IMO, post 10 in that link misses the mark - there is no such thing as altering the ratios of overlap areas in an effort to make these areas representative of the data. The text is all that matters. As for doing so in Access, I think your only option would be to use a control that would allow you to reproduce the diagram image. However, you'd need to create the diagram in Excel (or maybe Word) in the first place, so IMO it would be pointless to even try to get the sheet into a control. At best, I'd provide a way to open the Excel sheet from Access OR turn the diagram into an image and use a picture control in Access to contain it. Of course, it would be a static diagram in that case.
The more we hear silence, the more we begin to think about our value in this universe.
