These visualizations can be controlled through intuitive UI elements, allowing users to:

Adjust animation speed to focus on specific transformation steps
Toggle between different representation formats (e.g., matrix, index notation)
Zoom in/out and rotate 3D visualizations for better understanding
Step through transformations frame-by-frame for educational purposes
Export animations or static images for use in presentations or publications
