I'm able to import objects into a diagram from Excel without a problem; however, I also want to define connections (just lines - what object the line starts from, and what object it goes to) in Excel as well, so I don't have to draw them manually.
How do I go about doing this? How should I define that in my Excel spreadsheet, and how should I import those relationships into Visio?
I'm on Visio 2013 Professional.
