D2 is a diagram scripting language that turns text to diagrams. It stands for Declarative Diagramming. Declarative, as in, you describe what you want diagrammed, it generates the image. 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 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. 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. D2 is designed to be extensible and composable.
