D2 render example




Rendered with the TALA layout engine.






For more examples, see ./docs/examples.




Quickstart


The most convenient way to use D2 is to just run it as a CLI executable to
produce SVGs from 
.d2
 files.


# First, install D2
curl -fsSL https://d2lang.com/install.sh | sh -s --

echo 'x -> y -> z' > in.d2
d2 --watch in.d2 out.svg


A browser window will open with 
out.svg
 and live-reload on changes to 
in.d2
.


Install


The easiest way to install is with our install script:


curl -fsSL https://d2lang.com/install.sh | sh -s --


You can run the install script with 
--dry-run
 to see the commands that will be used
to install without executing them.


Or if you have Go installed you can install from source though you won't get the manpage:


go install oss.terrastruct.com/d2@latest


You can also install a release from source which will include manpages.
See ./docs/INSTALL.md#source-release.


To uninstall with the install script:


curl -fsSL https://d2lang.com/install.sh | sh -s -- --uninstall


For detailed installation docs, see ./docs/INSTALL.md.
We demonstrate alternative methods and examples for each OS.


As well, the functioning of the install script is described in detail to alleviate any
concern of its use. We recommend using your OS's package manager directly instead for
improved security but the install script is by no means insecure.


D2 as a library


In addition to being a runnable CLI tool, D2 can also be used to produce diagrams from
Go programs.


For examples, see ./docs/examples/lib.


Themes


D2 includes a variety of official themes to style your diagrams beautifully right out of
the box. See ./d2themes to browse the available themes and make or
contribute your own creation.


Fonts


D2 ships with "Source Sans Pro" as the font in renders. If you wish to use a different
one, please see ./d2renderers/d2fonts.


Export file types


D2 currently supports SVG and PNG exports. More coming soon.


Language tooling


D2 is designed with language tooling in mind. D2's parser can parse multiple errors from a
broken program, has an autoformatter, syntax highlighting, and we have plans for LSP's and
more. Good language tooling is necessary for creating and maintaining large diagrams.


The extensions for VSCode and Vim can be found in the Related section.


Plugins


D2 is designed to be extensible and composable. The plugin system allows you to
change out layout engines and customize the rendering pipeline. Plugins can either be
bundled with the build or separately installed as a standalone binary.


Layout engines:
  • dagre (default, bundled): A fast, directed graph layout engine that produces layered/hierarchical layouts. Based on Graphviz's DOT algorithm.
  • ELK (bundled): A directed graph layout engine particularly suited for node-link diagrams with an inherent direction and ports.
  • TALA (binary): Novel layout engine designed specifically for software architecture diagrams. Requires separate install, visit the Github page for more.

D2 intends to integrate with a variety of layout engines, e.g. 

dot
, as well as single-purpose layout types like sequence diagrams. You can choose whichever layout engine you like and works best for the diagram you're making.
