Editing Dia (software) (section)

== Features ==
Dia has a modular design with several shape packages available for different needs: [[flowchart]], [[Computer network diagram|network diagram]]s, [[circuit diagram]]s, and more. It does not restrict symbols and connectors from various categories from being placed together.<ref>{{Cite web |date=2021-12-18 |title=Network Diagram Open source SW |url=https://discussion.fedoraproject.org/t/network-diagram-open-source-sw/77480 |access-date=2025-03-12 |website=Fedora Discussion |language=en}}</ref>

Dia has special objects to help draw [[entity-relationship model]]s, [[Unified Modeling Language]] (UML) diagrams, [[flowchart]]s, network diagrams, and simple electrical circuits. It is also possible to add support for new shapes by writing simple [[XML]] files, using a subset of [[Scalable Vector Graphics]] (SVG) to draw the shape.<ref>{{Cite web |title=Dia (software) |url=https://www.seomastering.com/wiki/Dia_(software) |access-date=2025-03-12 |website=www.seomastering.com |language=en}}</ref>

Dia loads and saves diagrams in a custom XML format which is, by default, [[gzip]]ped to save space. It can print large diagrams spanning multiple pages<ref>{{cite web |url=https://www.openhub.net/p/dia/links |title=Dia |work=ohloh |publisher=Geeknet, Inc. |access-date=2010-05-30}}</ref> and can also be scripted using the [[Python (programming language)|Python programming language]].
