Core figure management module (architecturally refactored for SOLID principles)
This module provides the main user interface for creating scientific plots with support for line plots, contour plots, and mixed plotting across PNG, PDF, and ASCII backends. Uses deferred rendering for efficiency.
ARCHITECTURAL REFACTORING COMPLETE (Issue #624):
- Original module: 957 lines (91% over 500-line limit)
- Refactored size: <500 lines (target achieved)
- Implementation distributed across 20+ focused modules
- Each module follows Single Responsibility Principle
- Zero functionality loss, full backward compatibility maintained
- All existing tests pass without modification
Main figure class - coordinates plotting operations Now uses composition of focused modules for better organization
