Hi Joe, not sure Tableau is the best tool for this. You might want to take a look at packages that support networks, such as NodeXL: Network Overview, Discovery and Exploration for Excel - Home (I found this project via SNAP: Stanford Network Analysis Project).
I will try right now. I am soooo in over my head with this!!!

Thank you. I'm impressed recommending other companies products. Most
aboveboard. I looked into graphviz and as far as I can tell it calls for
writing code so .... enough said about that. You find me watching a utube
on NodeXL. Frustratingly, I have seen on the Tableau gallery just what I
am trying to accomplish but I cannot find instruction on . Maybe some day
Tableau could post a sample data set to match each gallery image?
Anyway, thanks so much for your help and have a great day

Both gephi and graphviz are free of charge, so the product term is not adequate. Both require to put your data in a special format, is not so difficult.
But nodexl is a plugin for excel so it is more easy to deal with.
Hope this helps.
Although something more specialist might be the easiest solution, the thing I love about Tableau is that as it's essentially a XY coordinate plane, you can use this to create Chart types that are 'Show Me' supported. I've recently done a network chart for our office footy table, using the 'path' shelf you can get Tableau to plot in the order you want.
Here is an image of our Footy network! I've deliberately left the Column and Rows shelf so you can see how I've brought in X & Y coordinates for each player (I've calculated these based on the formula for a circle, but you can code them into the source data). Below are also some of the best Network charts I've seen on Tableau, all with full instructions, and workbooks (the last one might not, but has step by step instructions)
Those are some great looking graphs . Soccer ball- like one with the
different thickness of lines is something that seems very relevant to my
idea. I am going to take a deep breathe, see if I can find my Patience,
and try to learn how to apply it my data. Thank you for taking all of the
time to send me such a thorough reply. Joe

Glad it was of help...the fact it ended up looking like a football was a happy Viz accident...Nice when that happens!
I plan to post our final footy dashboard to the Public area (just need to find a few hours to apply the final polish), where you'll be able to download the model, and see how it's put together (I'll make a note and let you know when it's up...hopefully in the next week or so).
Yes the Key part here is that the X/Y coordinates for each Node (person in my example) form part of the Person Master Data, so that every instance of each Node has the same X/Y. As you can then see I've created one chart, which is a line chart, with the Path as the connection (in my example I have a Team A Column, and Team B Column, and so create a calculated field in the form [Team A] + ' To ' [Team B]) which I put on the path tile). The second chart is a Shape Chart (where the shapes are imported images of each player), and then I Dual Axis/Synchronize Axis to get the desired result.
Best of Luck
Good Morning From Long Island, NY USA,
Yes , pls do send me a heads up when you post the polished football.
All the best,
