Chord Chart - Data Preparation

I would love to use the chord chart to analyse how people are interacting.  

Essentially, I have two tables:

One Showing Individual Thank You's (Initiated by Employees) giving thanks  (1 Employee can give 1 Thanks at a time)

The other are for those being thanked (1 Thank you from 1 employee could result in 5 other employees being thanked)

I would like to use the chord chart to corrilate the relationship between thanks sending thanks, and those recieving thanks.  I understand that to do this, I need a simple table of:

Those Thanking / Whome is Getting Thanked / How Often this Unique Combination is Occuring

This is where I am stuck.........    I assume I will need to create a calculated table (Or Maybe better in M Query), but I'm not sure how I go about creating the table, or even what to google  (I've tried to no avail).  Essentially I need some kind of unique combination for every persons relationship whether thanking or being thanked (But in two seperate Columns), and then I need to count how often this occurs in the data, and write the value in the 3rd Column.....

Could someone give me some hints as to how I might build this,?

Thanks
