Making diagrams can be quite a pain, especially if you do not have the proper and user-friendly software to help you draw it for you. How else can you make those lines straight and those boxes properly aligned so that they look neat and easy to understand?

Not to worry anymore – Dia comes to you to save the day. And we promise your boss or professor would awe at your professional looking diagrams.

Quite inspired by Microsoft Windows’ Visio, Dia is an open source software based on GTK+ for Linux, Unix and Windows which creates diagrams. Draw entity relationship diagrams, flowcharts, network diagrams and a whole lot more in total ease. You can even add your own shapes by writing XML files.

It is a great opportunity for those who constantly make diagrams, especially for presentations or for companies, because Dia is totally free – unlike Visio. Moreover, it is very easy to use, as well, so you can make your diagrams in no time.

Dia exports finished diagrams to EPS, SVG, DXF, CGM, WMF, PNG, JPEG and VDX so users who work both in Visio and Dia can work together. This makes collaborations easier, although there might be some compatibility problems – but the general file types are always there for backup.

Dia also allows you to print large diagrams on multiple sheets so you get to have one, big diagram when you put them all together – extremely useful for those really big flowcharts that you see in companies.

Dia is a simple tool which can really make your diagrams stand out and more understandable – and yes, everything is for free. However, it won’t hurt if you wish to donate.
