## What it is
D2 is a modern declarative diagram scripting language that turns plain text descriptions into diagrams. It ships as a CLI compiler with themes, multiple layout engines, and export formats like SVG, plus a library for embedding.

## Use cases
- generate architecture diagrams from text
- diagram as code for documentation
- convert d2 script to svg
- draw network diagrams declaratively
- create animated diagrams from text
- version-control software architecture diagrams

## When to choose
- you want diagrams maintained in version control as text
- you need polished, themed diagrams for docs, wikis, or presentations
- you want a fast text-to-diagram workflow with a CLI and playground

## When to avoid
- you need freehand or WYSIWYG diagram editing
- you require diagram formats D2 does not export
- you need a GUI-only diagramming tool for non-technical users
