Dia on Raspberry Pi & Chromebook
Dia Diagram Editor is a free, open-source project by the GNOME community. This site is an independent community resource — we are not affiliated with the GNOME Dia project.
Dia is a native GTK Linux application, which makes it a natural fit for ARM boards and Linux-on-Chromebook setups — no emulation, no hacks. This page covers both.
Raspberry Pi
Install
Raspberry Pi OS is Debian-based, so the standard package just works:
sudo apt update sudo apt install dia
Launch it from the desktop menu (Accessories/Graphics) or run dia in a terminal.
What to realistically expect
- Small to medium diagrams (class diagrams, flowcharts, home-network maps): perfectly usable, even on a Pi 3.
- Very large diagrams (hundreds of objects, poster-size exports): expect slower redraws — a Pi is not a workstation. Keep diagrams focused and split big ones across pages.
- Display: Dia is an X11/GTK app; it runs fine under Pi OS’s desktop. If you’re on the Lite (headless) image, there’s no GUI to run it in — install the desktop first or use Dia on another machine.
Chromebook
Install via Linux (Crostini)
- Enable Linux: Settings → Advanced → Developers → Linux development environment → Turn on.
- In the Terminal app:
sudo apt update && sudo apt install dia - Dia appears in your launcher under “Linux apps”.
What to expect
Dia runs in the Chromebook’s Linux container as a normal X11 app — diagramming, saving, and exporting all work. File sharing between ChromeOS and Linux files works through the Files app’s “Linux files” section, so getting diagrams in and out is painless. Performance is fine for typical school/office diagrams.
Syncing diagrams
.dia files are tiny (gzipped XML). Sync them with whatever you already use — Google Drive, Nextcloud, git. Just avoid editing the same file on two machines simultaneously; Dia has no merge.
FAQ
Is there an official ARM build of Dia?
There’s no separate ARM download — but there doesn’t need to be. The dia Debian package is architecture-independent in practice and installs cleanly on Pi OS.
Does Dia work on Chromebook without Linux mode?
No — Dia is a desktop Linux/Windows/Mac application, not a web app. On a Chromebook you need the Linux container (or use draw.io in the browser instead).
Can a Pi handle Dia’s Python scripting?
The Python console works the same as on any Linux install. Heavy batch exports will just be slower — fine for occasional use.
My school Chromebook blocks Linux mode. Options?
Ask IT to enable it (it’s a standard admin toggle), or use the portable Windows version (Dia Portable) on lab PCs, or draw.io in the browser.
