Add file size histogram generation script and analysis report

[Copilot]

This PR adds a comprehensive file size analysis tool for the repository, including a histogram visualization and detailed statistics.

Overview

Generated a histogram chart that visualizes the distribution of file sizes across all 5,615 files in the repository, providing insights into the repository's structure and composition.

What's Included

1. Histogram Chart (file_size_histogram.png)

• High-quality 300 DPI visualization using logarithmic scale
• Shows distribution of file sizes from 0 bytes to 16.6 MB
• Includes embedded statistics box with key metrics
• Clear visualization of the repository's file size distribution

2. Python Script (generate_file_size_histogram.py)

• Automated tool to analyze repository file sizes
• Walks through all repository files (excluding .git directory)
• Uses matplotlib and numpy for professional visualization
• Generates both chart and console statistics
• Fully documented with docstrings and comments

3. Analysis Report (FILE_SIZE_ANALYSIS.md)

• Complete documentation of findings and insights
• Full source code listing for reproducibility
• Usage instructions and dependency information
• Key statistics and observations

Key Statistics

• Total Files: 5,615
• Total Size: 158.6 MB
• Mean Size: 28.9 KB
• Median Size: 1.8 KB (significantly lower than mean, indicating a few large files)
• Max Size: 16.6 MB (compiled gh-aw binary)

Insights

The histogram reveals a typical software repository distribution:

• Most files are small (1-10 KB range) - primarily source code, configs, and docs
• A few large files include the compiled binary, Node.js dependencies (esbuild), and TypeScript libraries
• Logarithmic scale effectively visualizes the wide range from bytes to megabytes

Usage

To regenerate the histogram:

pip install matplotlib numpy
python3 generate_file_size_histogram.py

This tool can be useful for:

• Repository size analysis and optimization
• Identifying large files for cleanup or Git LFS migration
• Understanding repository composition
• Tracking size growth over time

Original prompt

Generate a histogram chart of the file sizes in the repo.

Report the chart image and the code used to generate it.

Summary Statistics:

• Total Files: 5,617
• Total Size: 158.8 MB
• Mean Size: 29.0 KB
• Median Size: 1.8 KB
• Max Size: 16.6 MB
• Min Size: 0.0 B

Histogram Chart:

The histogram shows that most files in the repository are small (1-10 KB range), with a logarithmic distribution typical of software repositories. The peak around 1 KB represents the majority of source code files, configuration files, and documentation.
