🌟 Summary

Enhancements to plotting utilities, including environment-aware font management and reduced download verbosity.

📊 Key Changes

• Added os and rearranged import statements for better organization.
• Introduced a RANK environment variable to control conditional font downloading.
• Modified font download function to disable progress output, streamlining the process.

🎯 Purpose & Impact

• 🔒 Font Download Control: By checking the RANK value, the system avoids unnecessary font downloads across distributed training nodes, potentially saving bandwidth and reducing clutter.
• 🚀 Performance: Disabling progress display during font download leads to a less verbose console, which is especially beneficial for users who are running scripts in automated environments or with logging.
• ✨ Consistency and Organization: Reordering the imports improves the code consistency and may slightly aid in understanding the module's dependencies for future development.
