# Intersections: Eulero-Venn chart or Alternative?

Hi guys,

It's been a while since the first time I've thought about an Eulero-Venn chart to visualize intersections.

What I would like to show is to "visually measure" the amount of (let's say) records which have a value A, value B or both values for a specifc category.

Example:

ID           TYPE

1             A

2             A

3             A

4             B

5             A/B

6             A/B

7             A/B

In a Eulero-Venn Chart there should be 2 circles:

circle A (6 records)

circle B (4 records)

with an intersections of 3 records

I've already tried to draw circles using poligons, but I can just draw circle A and B with sizes according to the number of records count (eg: A=6 and B=4)

My real problem comes when I have to intersect them in order to draw a correct interesction size (eg: 3).

I can't find a way to "place" those 2 circles in order to have an intersection size equal to 3.

Do you guys think there's a way to visualize this chart or you think there's a more simple better way with another chart?

Any help would be appreciated.

Fabio

Thank you for your time, and pretty interesting article

I've got a question: may I ask you why 2 "interesctions" of the same size have differente numeric values?

Example: Consumer and Corporate, for example have the same size but the first one has numeric value of 1.5M and the second has 2.3 M value.

I'm asking because my REAL problem is to find a way to make intersections size according to values.

Best
