Chart to represent SQL Table Join

Here's the back ground - I'm going to be training someone on how to use an HRIS query system. That involves tables and join statements. I want to demonstrate the difference between join statement through excel. I'm not sure that this can be done in excel but I want to find out.

Anyway, I've created a test spreadsheet. My thoughts are I can do this through various lookups. What I was wondering is, is it possible to either have a chart or a picture where I select on the picture and it brings up the various columns.

So, I select the 'inner' circle and it shows me the employees on the Job Data tab who are also on the Sensitive data tab (and the appropriate columns). I select the 'left' circle and it shows me only the employees on both tabs and all the columns.

An example of the circles below.

Is this at all possible??
