Draw.io Flowchart Generator

Problem

Manually arranging nodes, edges, alignment, and labels in draw.io can be tedious, especially when converting a process description, interface flow, or business rule into a maintainable diagram. This skill turns text or file descriptions into structured chart data and exports an editable .drawio file, reducing the upfront cost of drawing from scratch.

How It Works

• Accepts text or file input and first generates a structured JSON model with nodes and edges for review.
• Node types include start, end, process, decision, document, and data; edge labels support Yes / Y, No / N, or empty for sequential flow.
• After confirmation, it calls scripts/gen.py to generate the .drawio file. The underlying generator.py emits XML, while references/drawio-xml-spec.md documents style and attribute conventions.
• Layout parameters such as CANVAS_WIDTH, _LAYER_GAP_Y, and MAIN_X can be adjusted for layer spacing and main axis position; more compact A4-style output can be tuned by changing the relevant globals before generation.

Limits

The output is a practical first draft, not a polished diagram. Lines may overlap, node spacing may be uneven, and automatic alignment may need correction. It is best for quickly turning process, state, or data-flow descriptions into editable draw.io artifacts, then manually refining them. It is not intended as a high-fidelity architecture diagram tool, and you should not bypass gen.py to call the low-level generator.py directly.
