D2 is a modern declarative diagram scripting language that converts plain‑text definitions into visual diagrams. It provides a fast CLI, a Go library, and an npm package for generating SVG, PNG, and animated diagrams.

Use cases

• Create architecture diagrams from simple text files
• Generate flowcharts and network diagrams programmatically
• Render SVG diagrams for inclusion in markdown documentation
• Produce animated diagrams for presentations
• Automate diagram generation in CI/CD pipelines
• Embed system component visualizations directly in code repositories

When to choose

• You need a lightweight, scriptable way to produce diagrams without a GUI
• You prefer a declarative text format that can be version‑controlled
• You want to integrate diagram generation into build scripts or CI pipelines
• You require fast rendering with support for themes and multiple output formats

When to avoid

• You need an interactive drag‑and‑drop diagram editor
• Your diagrams require complex 3D or real‑time simulation capabilities
• You only want a WYSIWYG tool with no scripting support
