I have two systems I use on a regular basis. I use one for presentations and the other I use to do my work. I have Visio on my main system but I do not have it on my other system I am using for the presentation. Is there a way to open these diagrams so that I can display the content without having the full up version of Visio installed?
You can use Microsoft's Visio viewer. You can also use Lucidchart's Visio Viewer functionality which is an online application that imports/exports Visio files.
That would allow you to also make changes, if necessary, to your diagram when you don't have access to Visio.
