Need a simple diagramming tool ?

A client recently requested a simple tool for generating data diagrams as part of a project. They wanted something simple and preferably inexpensive as it would be needed to be used by a large group of team members. Tools like Visio were too expensive in this case and more complex than the client needed. After researching a few options I came across DIA and found that this tool was pretty much exactly what they were after.

Dia is roughly inspired by the commercial Windows program ‘Visio,’ though more geared towards informal diagrams for casual use. It 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 is also possible to add support for new shapes by writing simple XML files, using a subset of SVG to draw the shape.

It can load and save diagrams to a custom XML format (gzipped by default, to save space), can export diagrams to a number of formats, including EPS, SVG, XFIG, WMF and PNG, and can print diagrams (including ones that span multiple pages).
