Demonstration of subplot functionality using the stateful API
This example demonstrates: - 2x2 subplot grid layout with sin, cos, damped oscillation, and quadratic functions - 1x3 subplot horizontal layout with linear, quadratic, and cubic functions - Independent titles and labels per subplot - Different mathematical functions visualized in each subplot
API Usage: - subplot(rows, cols, index) to create subplot grid and switch to specific subplot - plot(), title(), xlabel(), ylabel() work within current subplot context - savefig() renders entire subplot grid to output file
