Drawio Automatic Diagram Assistant

Problem

When the task is to render a service dependency map or system flow, hand-writing draw.io XML often produces misplaced nodes, overlapping edges, and brittle revisions. please-drawio-turn targets that workflow: it accepts natural language, structured JSON, or example-based instructions and produces a .drawio file suitable for architecture diagrams, flowcharts, UML class diagrams, ER diagrams, sequence diagrams, mind maps, network topologies, and org charts.

How It Works

• Natural language to diagram: identify the diagram type, extract nodes and relationships, then produce a layout plan.
• Unified layout engine: use topological layering, barycentric ordering within layers, dynamic spacing, and obstacle-aware routing to reduce crossings and overlaps.
• Confirm-first workflow: run through Think, Confirm, and Iterate; simple linear flows or explicit JSON spec inputs can skip confirmation.
• Version rollback: save a checkpoint before each update, keep up to five versions, and restore or compare previous states.
• Enforced hooks: backups, version initialization, cleanup, and preview launch are handled by Python hooks rather than relying on model compliance.

Boundaries

It generates draw.io source files instead of editing .png or .jpg images. It is not intended for Mermaid or other explicitly requested tools. The materials also note known layout issues, such as polar-coordinate child positioning, so complex diagrams should be reviewed and refined iteratively.
