+# Disk Usage Visualizer (CLI)
+
+A simple Python script that scans directories and displays the largest folders or files by disk usage — right from your terminal.
+Lightweight, fast, and cross-platform (works on Linux, macOS, and Windows).
+
+## Features
+
+- Recursively analyzes disk usage in a directory
+
+- Displays top N largest folders (default: 10)
+
+- Handles long file paths and permission errors gracefully
+
+- Works seamlessly on Windows, Linux, and macOS
+
+## Usage
+
+```bash
+# Analyze current directory
+python disk_visualizer.py
+
+# Analyze a specific path
+python disk_visualizer.py D:\Projects        # Windows
+python disk_visualizer.py /home/user/docs    # Linux/macOS
+
+# Show top 20 largest folders
+python disk_visualizer.py . -n 20
+```
