title: Visio: Setting connectors or relationships with Excel data source
body: <p>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.</p>
  
  <p>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?</p>
  
  <p>I'm on Visio 2013 Professional.</p>
