Instructions:
• Adjust the polynomial degree slider to control model complexity
• Use L1 regularisation (Lasso) to encourage sparse coefficients
• Use L2 regularisation (Ridge) to shrink coefficient magnitudes
• Click anywhere on the plot to add new data points
• Use "Generate New Data" to create 5 random points
• Use "Clear All Data" to remove all points
• Observe how regularisation helps prevent overfitting
