Editors' Review


Technical flowcharts and diagrams are a great way for IT project managers to visually demonstrate the ins and outs of a project to all involved. Dia lets users quickly draw customized flowcharts and diagrams. While the program markets itself toward a more technical crowd, we think it's a great tool for just about anyone looking to create a custom flowchart.

At first glance, there's a lot to Dia's user interface, especially if you're not familiar with image-editing tools. But a visit to the ample Help menu, and especially to the Quickstart section, will have you up and running in no time. The window opens with a blank, gridlike "canvas" in the center. A toolbar sits at the top with various edit, view, and layers options. A toolbox with tools for adding text, scrolling, magnifying, and adding shapes and lines resides below that, as do various objects used for creating a basic flowchart or technical diagram. We immediately jumped in and added specific shapes that represented technical commands, connecting them with lines. For example, the diamond object represents "Decision," while the circle represents "Connector." From there, we were able to customize our flowchart by adding colors to our shapes as well as text. Dia has the ability to create diagrams using UML, or Unified Modeling Language, as well as a long list of other special object categories such as Cisco, Database, and Sybase.

Dia's wide swath of technical objects makes it perfect for IT professionals, but its basic tools and ease of use make it appropriate even for non-techies. Dia installs and uninstalls cleanly and without issues. We highly recommend this program for all users.

"report problems when using international characters"

October 02, 2011  |  By tcccc

 |  Version: Dia 0.97.1


As an engineer, I think the layer property is attractive even if I haven't use the function.


the user's experiences after installation need to be enhanced.


The first look of the software has rule on both x and y direction.
I wonder the unit of the rules I image a chart within A4 size. I need a boundary for my layout.
I installed it on my desktop(vista home premium sp2 in Japanese). The first try with Japanese characters finally works after a hard experience to change the IME from Dia's menu and font at chart's properties. Actually I did not know where is the point to make it to accept Japanese characters.
When I made another new diagram, it refused to accept Japanese any more. Sure I tried hard to repeat my experience on the first diagram.

"Learn the UI, it gets the job done."

July 15, 2011  |  By mstrems

 |  Version: Dia 0.97.1


I have used visio professionally to define business process flow diagrams. I can do with Dia almost anything I used to do with Visio. No prob to report. Can be installed on Windows or Mac platforms since it is java based.


User interface can be frustrating at time. I recommend to search online when you have a question with Dia.
As usual, the more you use it, the easier it gets...


I chose Dia because I wanted a free solution to develop diagrams for my start up (using those as part of functional requirements)
The outcome is not picture perfect as with Visio, but you will get the job done. I recommend this software if you have some experience with Visio, want a free solution w/o strings attached and are willing to invest the small upfront time to master the interface. If you are creating your first process flow, check the free offers on https://www.lucidchart.com/users/registerLevel.
