Relationship visualization between selected groups

Dear All,

I am working on a data visualization between selected groups (A, B, C) by shared resources (1, 2 ,3).

When selecting A and C, it would need to show the shared values from the resources, 1,2,5,etc.

Also listing the values that are unique by the group. I looked at the decomposition tree and other relationship models but none of them worked out.

Does anyone have a suggestion?

Thank you.
