Figure Bĭiagram Designer ( Figure C) is another freeware tool that suffers (like Dia) from looking a bit on the outdated side. Dia is also available for Linux, Mac, and Windows. Dia loads and saves XML formatted documents that are gziped by default to save space. Like CADE, Dia was inspired by Visio - but with a much more casual approach and feel. Dia ( Figure B) is an open source, GTK+ diagramming tool that has a shallow learning curve and can help you create basic network diagrams.
