DIA, Freeware Program to Draw Structured Diagrams

Dia is an open source diagramming software, inspired by the commercial program Microsoft Visio. Dia can be used to draw many different kinds of diagrams.

It currently has special objects to help draw entity relationship diagrams, UML diagrams, flowcharts, network diagrams, and many other diagrams.
It can load and save diagrams to a custom XML format (gzipped by default, to save space), can export diagrams to EPS or SVG formats and can print diagrams (including ones that span multiple pages).
