Whats the difference between Inkscape and Dia?
Dia is for technical diagrams like database charts, class diagrams, etc., whereas Inkscape is for vector drawing such as logos, posters, scalable icons, etc. SVG is a useful format for creating diagrams, though, so we hope as Inkscape grows as a fully-featured SVG editor, it will also be useful for making attractive diagrams too. Several of us hope Inkscape will become a useful technical drawing tool and work on features with that goal in mind. However, Dia provides a number of useful capabilities such as support for UML, autogeneration of diagrams, etc. that are well beyond the scope of a general SVG editor. Ideally both Inkscape and Dia can share various bits of code infrastructure and third party libraries.
