This article is about the diagram-creation software. For other meanings, see Dia (disambiguation).
Dia is an open-source general-purpose diagram creation software program, developed as part of the GNOME project. Dia was originally created by Alexander Larsson. Dia uses a Controlled Single Document Interface (CSDI) similar to the GIMP and Sodipodi/Inkscape.

Dia is conceived in a modular way with several shape packages for different needs: flowchart, network diagrams, circuit diagrams, etc. Dia does not restrict symbols and connectors from various categories from being placed together.

Dia diagrams are very easy to create and export to multiple formats. The Windows program Microsoft Visio among others serves a similar purpose. 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 simple circuits. It is also possible to add support for new shapes by writing simple XML files, using a subset of SVG (Scalable Vector Graphics) to draw the shape.

Dia loads and saves diagrams to a custom XML format (gzipped by default, to save space). Dia can export diagrams to various formats including Encapsulated PostScript (EPS) or SVG, Drawing Interchange format (DXF), CGM, amongst others.

Dia can print diagrams including very large diagrams that span multiple pages. Dia can be scripted using the Python programming language.
