D2 Diagram Generator

When to Use

• Generate architecture diagrams from Terraform or Terragrunt code
• Visualize Azure infrastructure with proper icons, connections, and grouping
• Create .d2 files rendered to SVG/PNG via the d2 CLI
• Represent resource dependencies, network topology, RBAC, monitoring, and data flows

Goal

Create readable architecture diagrams using D2 language for Azure/Terraform infrastructure. Output is .d2 text files, rendered to SVG or PNG via the d2 CLI.

Tools

• d2 CLI: Render .d2 files to SVG/PNG: d2 input.d2 output.svg
• d2 CLI with layout engine: d2 --layout=elk input.d2 output.svg
• d2 fmt: Format D2 files: d2 fmt input.d2
• No MCP server is used — the skill generates D2 source code as text.
