How to Create a Venn Diagram

A Venn diagram uses overlapping circles to illustrate the logical relationships between two or more sets of items. They depict how things relate to each other within a particular segment.

For example, how many customers made purchases in the East region, in the West region, and in both regions?

Where the circles overlap, you display text or a value the represents the value associated with the relationship.

Venn diagrams are also called Set diagrams or Logic diagrams.

Thanks for your point of view, Andy, but the chart you made actually misrepresents the data behind it. It would be great to add a few steps and as a result get a real proportion of east, west and both regions order count from this type of chart. And that would be the hardest part

Hi Andy, I wanted to do a similar analysis to show how many customers purchased on both channels. I was wondering if there's a better visualization for this scenario. Venn diagram is very straightforward for sure, but Tableau doesn't seem friendly to make it.

Thanks for the video Andy, how can we interpret calculation of combinedPucrhases if we want to draw venn diagram for 4 regions all together.

Hi Andy! Thank you for sharing your knowledge! I was wondering the possibility of building a Venn Diagram with more intersections what do you think?

Thanks for a great tip. I had hoped to get the real proportion but nonetheless it will be a useful visualisation of the overlap. But I'm stuck at a really silly point. At 1:37 you say "I'm just gonna drag the view down a bit so we can see it a bit better". Mine won't drag. What would be stopping it? I can do the steps that come afterwards.

When we drag the calculation from measure to dimension and then change it to continuous what change does this make? ( When it is in measure it shows the sum of all 1's and 2's. Is it this way? )
