Summary

This PR migrates several Mesa tutorials (4, 5, and 6) to the new SpaceRenderer API. It resolves deprecation warnings by replacing the older draw_* methods and parameterized render() calls with the recommended setup_* methods and a parameterless render() call

Bug / Issue

The tutorials were still using the deprecated visualization API. Specifically:

• They used draw_structure() and draw_agents() instead of the new setup_structure() and setup_agents() methods.They passed portrayal arguments directly to .render(), which is now deprecated in favor of a "setup then render" workflow.
• This causes PendingDeprecationWarning and FutureWarning for users following the tutorials and inconsistent teaching of the library's best practices.

Implementation

Updated the following Jupyter notebooks:

1. docs/tutorials/4_visualization_basic.ipynb:
   • Updated Cell 16 to use method chaining for setup: .setup_agents(agent_portrayal).render().
2. docs/tutorials/5_visualization_dynamic_agents.ipynb:
   • Updated Cell 14 to use: .setup_agents(agent_portrayal).render().
3. docs/tutorials/6_visualization_rendering_with_space_renderer.ipynb:
   • Code Cells 15 & 18: Migrated both Matplotlib and Altair examples to the multi-step pattern: setup_structure(...), setup_agents(...), and then render().Markdown Cells: Updated all text references to reflect the method name changes (changing draw_structure() to setup_structure() and draw_agents() to setup_agents()) to ensure instructional consistency.

Testing

• Verified that all code changes align with the implementation source in mesa/visualization/space_renderer.py.
• Checked that Markdown references correctly match the updated code snippets.

Additional Notes

This migration ensures that the "setup then render" paradigm is taught consistently across all core spatial visualization tutorials.
