Quality of Diagrams

Well, quality of the graphic images/icons are good but compared to other tools, they are a little archaic. Icons are very basic and richness of the graphic quality could be improved. But, overall, Dia is a great tool and it is pretty reliable too. It can work as an alternative to Microsoft Visio.

    Really great article! Visio is cool, but I find Creately useful too. Their flowchart templates are quite great – http://creately.com/diagtype/flowcharts

    I like dia, but I’ve yet to be able to create template pages that always comes up defaulting to one visual (and printed) page with a heading and date. In Visio I created wide and portrait templates.

    It’s probably a matter that I rush to my work effort and don’t spend enough time to master the parms and options of dia. I’ll have to add that to my New Year resolutions.

    You should give Lucidchart a try! I used Lucidchart’s free network diagram tool and it was really easy to understand. If you use diagrams often you should check it out!
