statement-to-tikz

Geometry statement → constraint-solved TikZ (training-free pipeline).

This Hub card mirrors the GitHub project. Source of truth for code is the git repository.

What it does

1. Formalize olympiad-style plane geometry text into GeometryIR (JSON constraints).
2. Solve point coordinates with SciPy least_squares (gauge-fixed).
3. Emit TikZ; verify residuals; optionally compile PDF.
4. Fall back to schematic layout when exact solve fails.

Quick start

pip install -e ".[dev]"
stt "In triangle ABC, AB = AC, and D is the midpoint of BC. Draw the median AD." -o out/median

Set OPENAI_API_KEY for LLM formalization of arbitrary statements (stt ... --no-offline).

Not a trained model

v1 ships a pipeline + IR + solver, not fine-tuned weights. Fixtures under tests/fixtures/ are the evaluation seeds.
