Dia diagram is the smallest and simplest free tool for drawing a variety of shapes which makes the presentation of flowcharts easy. While comparing with other software, it provides a large number of shapes, thus making the preparation of slides and other flowcharts easier. This software can be used for many purposes.

Its interface and functions are very friendly and easy to use. The program includes printing several pages, exporting to many formats (EPS, SVG, CGM and PNG), and gives us the option to use custom created forms. The program is very useful for the elaboration of UML diagrams, network maps and flow diagrams. Diagram Editor Day is easy to learn and very efficient to use and observe the quality of the results, plus it is flexible enough to allow you to create highly customized diagrams.

The simplicity of the software is the most likely thing for me. Is so easy to use, easy to configure and easy to install. You can deploy every documentation or project using this software for the diagrams and draws of your network. Another important thing is that the free version has almost the same features as the paid version, so you can pay only if you need to. It has a variety of features and symbols and options by default, and if you need something additional you can download it quickly. Also, you can export your drawings in almost all the extensions and formats.
