Swiss Ephemeris Natal Chart Renderer

Problem

Many natal chart tools split text output and image rendering into separate code paths, so planetary positions, house cusps, and aspects can drift apart. Other scripts only print numeric results without a viewable chart. This skill targets workflows that need both machine-readable data and a display-ready PNG from one calculation source.

How It Works

• natal_chart_swe.py is the single calculation engine, using Swiss Ephemeris to compute planets, houses, aspects, ASC/MC, and related chart data.
• The --json flag exports structured results for renderers or AI pipelines.
• draw_wheel.py does not perform independent astrological calculations; it calls natal_chart_swe.py --json and renders a 5760×2880 chart with Pillow.
• The output includes a wheel, planet symbols, house lines, aspect lines, legends, and English/Russian interpretation panels; options include --name, --lang, and --conclusion.

Limits and Notes

• The runtime is fairly specific: Windows x64, Python 3.14, and the bundled native extension environment, so cross-platform use should be validated first.
• This is an astrology calculation and chart-rendering skill, not a general-purpose data visualization component; if only JSON is needed, use the calculation script directly.
• Interpretation text comes from the built-in bilingual data module, while --conclusion only renders an externally supplied conclusion file rather than generating one automatically.
