Generate a Vega-Lite chart specification from a teacher’s prompt using an LLM with structured JSON output. The result is validated against the Vega-Lite v6 JSON Schema; on failure the validation errors are sent back to the model for one repair round. Returns the specification pretty-printed as a JSON string.
