Total Noob question: I'm trying to use the Import Adjacency Matrix command to make a bubble diagram automatically. I'm using the sample Adjacency Matrix.csv that comes provided with the program. When I import it, I get a graphic of lines that I'm guessing represent links between spaces, but I do not see any spaces. Also in the Adjacency Matrix that is created, there are no room names, only the word "Custom" repeated for every line. I've used the exact settings that are recommended for the sample file (see picture), so I don't understand why my program isn't showing spaces. Can someone please tell me what I'm doing wrong? I've attached screenshots to show my settings and the results. It seems to get the adjacencies but isn't creating any spaces. Thanks!!!!
