Dia

Dia, as marketed by its developers, is a “drawing program” that allows people to create different diagrams using base elements or imported ones. Based on the Visio application, this tool increases the previous possibilities and provides more access to different features, as XML support has been added. Using XML files, users are no longer constricted to rely on the basic elements provided by the tool and they can create their own diagram elements. A guide is provided on the developer’s website and here, users are able to learn the basics of XML diagram elements.

Such diagrams can be mostly used to create professional presentations, although there are also other uses for them, depending on the needs of the user. Diagrams can be easily imported if they are gzipped and after users finish working with them, the end product can be exported using various formats, such as EPS, SVG or even PNG, making them cross-compatible with other applications. The interface is designed in order to provide multiple features without making the screen cluttered and difficult to navigate through. This way, users can easily find the needed tools that are required in the diagram making process.

The main toolbar is available in the left area of the screen and from here, basic shapes and tool can be accessed. However, advanced drawing tools are available from the View menu. Python scripts can be added to the application and they are relatively easy to use, depending on the skill of the user. Such scripts can also be developed if a feature that is required is not already covered by Dia. Printing files is also easy and various settings are available, especially regarding the document’s resolution and quality. Printing can be achieved using different services, one of them being Gnome.
