Using Force-Directed Graph only showing 2 parameters

[nafpic]

I'm new to Power BI and using Force-Directed Graph to visualize SQL graph tables.  However, it only shows the first 2 elements of the table.  For example, I can display the application name and server name or the application name and database name but not application, server and database names at on time

You can create a view or select multiple edge tables. For example, 

select n1.[col1], n2.[col2], n3.[col3]

from [node].[node1] n1, [edge].[edge1] e1, [node].[node2] n2 , [edge].[edge2] e2, [node].[node3] n3

where MATCH (n1-(e1)->n2-(e2)->n3)

Like a Sankey, a Force-Directed Graph has a "From" and a "To" value.  That's it.  How would you envision adding a third dimension column to that?
