[Aditya-Gupta26]

Adds a note to visualize.md file.

Greptile Summary

This PR adds documentation to visualizer.md explaining the zoom_in configuration parameter in the drive.ini file. The parameter controls whether the visualizer camera zooms into a portion of the map (when True) or displays the full map (when False).

What Changed:

• Added a new "Additional Note" section to the visualizer documentation
• Documented the zoom_in parameter from drive.ini
• Explained the parameter's default value and usage

Context:
The zoom_in parameter is defined in pufferlib/config/ocean/drive.ini (line 98) and is used by the rendering pipeline. When enabled, it passes the --zoom-in flag to the visualizer binary (visualize.c), which adjusts the camera's field of view accordingly.

Issues Found:

• The file path reference is ambiguous (should specify pufferlib/config/ocean/drive.ini)
• The section header "Additional Note" is vague and doesn't follow documentation naming conventions
• The description "looks off scale/position" is informal and could be more precise

Confidence Score: 4/5

• This PR is safe to merge with minor documentation improvements recommended
• Score of 4 reflects that this is a documentation-only change with no code modifications. The information provided is technically accurate and verified against the codebase (drive.ini, utils.py, and visualize.c). However, the documentation could be improved for clarity and specificity (file path ambiguity, informal language, vague section header). These are style issues that don't affect functionality.
• No files require special attention - this is a simple documentation addition

The file reference "drive.ini" is ambiguous. The project contains multiple .ini files (e.g., pufferlib/config/default.ini, tests/ini_parser/test_drive.ini, pufferlib/config/ocean/drive.ini). The documentation should specify the full path to avoid confusion.

Suggested change

	- The file `drive.ini` provides a `zoom_in` parameter. Its value is set as `True` by default but can be modified to `False` in case the displayed map over visualizer looks off scale/position.
	- The file `pufferlib/config/ocean/drive.ini` provides a `zoom_in` parameter. Its value is set as `True` by default but can be modified to `False` in case the displayed map over visualizer looks off scale/position.

The phrasing "looks off scale/position" is informal and vague for technical documentation. Consider being more precise about what this parameter controls. Based on the code in visualize.c, when zoom_in is true, the camera zooms in on a part of the map; when false, it shows the full map.

	- The file `pufferlib/config/ocean/drive.ini` provides a `zoom_in` parameter (line 98). Set to `True` by default, this zooms the camera into a portion of the map. Set it to `False` to display the full map view instead.

The section header "Additional Note" is vague and doesn't describe what the note is about. Consider using a more descriptive title that matches the pattern used elsewhere in the documentation (e.g., "Configuration", "Usage"). Since this section discusses configuration options, a more specific title would improve navigation.
