Pull Request Overview

This PR refactors the visual testing framework to improve test organization and leverage the contextily library for basemap rendering. The changes move away from a centralized create_visual_map function to individual test methods that directly use matplotlib and contextily for creating transit system visualizations.

• Replaces the comprehensive visual snapshot testing approach with more granular, system-specific tests
• Introduces contextily-based basemap rendering directly in test methods
• Restructures test fixtures to load individual transit system data separately
