I'm trying to create a thick border around the northwest counties of Illinois (Carroll, Jo Daviess, Lee, Ogle, Stephenson, and Whiteside) to show that's our coverage area. I know polylines can be manipulated to have a thicker border, so I dissolved the counties together in ArcPro and used the Polygon to Polyline tool to create a polyline shapefile. But it doesn't have any geographic coordinates associated with the lines, so Tableau won't use it. Can anyone provide assistance how to make this work?
I've attached my workbook and the polyline I created.

Thank you. I was trying to add it to the original data source, and it wasn't connecting properly. I didn't realize you could add unrelated data sources this way. Got a lot to learn.
