Dia for Windows is a free download that lets you create flowcharts, diagrams, and more. Also check out the Mac version here.

Need a neat flowchart for a class project? Dia is a free, open-source tool for creating diagrams and flowcharts, available for both Mac and Windows. In our test on Windows, we experienced no issues on a PC with Windows 7 64-bit.

One of the best things about Dia is its simple interface, which lets you quickly build the right diagrams and flowcharts. There are many types of lines, shapes, and other objects to work with, and just like in other programs, you simply drag them onto the blank canvas.

Overall, Dia feels like a solid app, and if you need to create flowcharts or diagrams for your project fast, it’s definitely worth the download.
