✅ Spec ID Assigned

Assigned ID: area-basic

Rationale: This is a new plot type (area chart) with basic features - a single filled area over sequential values. The ID follows the standard format: {plot-type}-{variant} and is concise and descriptive.

Next Steps:

1. A maintainer will review this request
2. Once approved (label: approved), code generation will begin automatically
3. Implementations will be created for all 8 libraries

Spec will be created at: specs/area-basic.md
