Dia is a GTK+ based diagram creation program released under the GPL license. Dia is designed to be much like the commercial Windows program 'Visio'. It can be used to draw different kind of diagrams. In this first version there is support for UML static structure diagrams (class diagrams) and network diagrams. It can currently load and save diagrams to a custom fileformat and export to postscript. WWW: http://www.lysator.liu.se/~alla/dia/ -- Marcin Cieslak
