Viz Skill: Data Visualization and Inspection

Purpose

This skill directly executes visualizations. The calling agent provides a visualization spec along with data context, and the skill:

1. Infers the data loading code from the provided context
2. Generates the complete plotting script
3. Executes it via the viz_runner.py helper
4. Returns artifact paths for the caller to reference

Key pattern:

Caller (with data context) → Skill (infers data loading, generates script, executes) → Plot appears

The caller does NOT need to write any execution code. The skill handles everything.
