Problem with opening Visio files

Whenever I try to open a Visio file in Draw, LibreOffce opens it in Writer, and only displays gibberish text. This happens with every .vsd file I’ve tried to open. I’m using LibreOffice version 5.1.0.3 on Windows 7. I’m trying to open Visio 2013 files. I’ve googled around and haven’t found an answer to this issue.

Thanks for the help.
