“When it comes to open source graphics tools, GIMP gets a great
deal of attention, and there are many free online resources
available for it, but if you’re in search of a free drawing and
illustration tool that can compete with Adobe Illustrator and is
increasingly useds by web designers for effects, logos and still
graphics, give Inkscape a try. It runs on Windows, Mac OS X, and
Linux, and is well-known as a powerful and flexible drawing and
vector editing application. We covered it and resources for getting
started with it in this post.“Dia is very similar to Microsoft’s Visio application, and was
developed as part of the GNOME project’s office suite. There are
many types of useful diagrams and flowcharts you can do in Dia. You
can associate multiple diagrams with each other and work on them in
tandem. Dia also exports diagrams in most popular graphics file
formats. We covered the application previously in this post.”
