Rendering ASCII architecture diagrams from D2 or Graph::Easy sources prevents messy misaligned box-art by inspecting the generated geometry first, ensuring accurate communication in Markdown documentation, PR comments, or terminal output.

Yes, you can render PlantUML sequence diagrams as ASCII art in terminal output by using PlantUML as the renderer for sequence-like flows, while D2 and Graph::Easy handle architecture and service flow diagrams.

The best way to fix misaligned ASCII box diagrams is using a diagram-first render-and-inspect workflow that generates a proper D2 or Graph::Easy source, renders it, and revises until the box-art geometry is correct.

D2 supports ASCII backend rendering for architecture diagrams, but this Skill applies safeguards to avoid common D2 ASCII backend pitfalls like multiline labels and dollar signs to ensure correct geometry.

You should use Graph::Easy instead of D2 for dependency and interaction maps when D2 is not appropriate, acting as a fallback renderer while maintaining short labels and simple structure for accurate ASCII output.

No external tools are strictly required to start rendering ASCII diagrams from D2 sources, as the Skill handles generation and inspection internally, though optional renderer toolchains like D2, Graph::Easy, or PlantUML can be used.
