feat: implement scatter-basic-006

[claude]

Summary

• Generated implementations for scatter-basic-006: Multiple Scatter Plots in Single Figure
• Created specification file based on issue #13 requirements
• Implemented both matplotlib and seaborn versions

Implementation Details

• Specification: Creates a figure with three scatter plots showing x vs y1, y2, and y3
• Matplotlib: Uses ax.scatter() with different colors for each series
• Seaborn: Uses sns.scatterplot() with seaborn styling

Self-Review Results

Both implementations passed self-review with scores ≥ 85:

• ✅ Matplotlib implementation: Score ~92/100
• ✅ Seaborn implementation: Score ~92/100

Quality Criteria Met

• ✅ All axes properly labeled
• ✅ Grid visible but subtle (alpha=0.3)
• ✅ Points clearly distinguishable (size=50, alpha=0.7)
• ✅ Legend included to distinguish three series
• ✅ Complete type hints and docstrings
• ✅ Input validation with clear error messages
• ✅ All spec requirements implemented

Test Plan

• Implementations tested locally with sample data
• Both generate plots without errors
• CI tests will run automatically
• Quality check workflow will evaluate implementations

Closes #13
