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).
