Architecture

PinViz architecture overview.

Design Patterns

1. Separation of concerns: Model → Layout → Rendering pipeline
2. Factory pattern: Boards and devices use factory functions
3. Immutable data: Data classes are immutable

Core Modules

• model.py - Core data structures
• boards.py - Board templates
• devices.py - Device templates
• config_loader.py - Configuration parsing
• layout.py - Layout engine
• render_svg.py - SVG rendering
• cli.py - Command-line interface
