figure-lab

Iterative visualization development lab. Composes novel D3 visualizations from marks, scales, and encodings — tests rendering — evaluates against user intent — promotes successful results to /create-figure as first-class commands.

Key Difference from Other Labs

Unlike /table-lab (parameter tuning) or /prompt-lab (prompt iteration), /figure-lab composes new visualization types from D3 primitives. The NOT_YET types in d3_catalog.py are the backlog — figure-lab develops and tests them until they work, then promotes them to implemented status.
