Love the Dia tool. Have been using it since 2002 for a variety of diagramming needs. Easy to use and very flexible. And today I learned something new. How to copy objects from one Dia diagram to another!! You guys rock!

I have used this free app to create many presentations. It is excellent. Best value for FREE. The only gripe I have is the level of difficulty in saving it in other formats, such as Power Point or PNG.

I would've given this software 5 stars if there was a "print review" function. Large flowchart plus inability to change display units to inches (so I didn't know the actual size to choose the appropriate paper) resulted in a few tries in paper sizes and scaling to get it right on the page - especially converting to pdf. Having said that, this little program was easy to use; had all of the functionality I needed to produce a flowchart and has a lot of different options for output formats. Just a little clunky in being able to size the output. I think this is pretty great software when your company doesn't want to pay for Visio. (There should be an "N/A" next to "Support" - it was so simple I didn't need Support so I gave it a "4").
