I've created a 3D visualization tool that allows you to:

1. Upload a CSV file containing 3 columns of numbers (x, y, z coordinates)
2. Visualize the points in a 3D space

3. Interact with the visualization using:

   • Left mouse button to rotate
   • Right mouse button to pan
   • Scroll wheel to zoom

The tool includes:

• File validation and error handling
• Axis visualization (X in red, Y in green, Z in blue)
• Points rendered in red
• A clean, minimal interface

To use it:

1. Prepare a CSV file with exactly 3 columns of numbers
2. Click "Choose File" or drag and drop your CSV
3. The points will automatically appear in the 3D view
4. Use your mouse to explore the visualization

Example CSV format:

The visualization will automatically scale to fit your data points. Let me know if you'd like any adjustments to the visualization, such as different colors, point sizes, or additional features!
