HTML Canvas Wave Line
This example demonstrates a sine wave pattern drawn on an HTML canvas element, showing how mathematical functions can generate visual curves. The wave oscillates vertically across the 800-pixel-wide canvas, centered vertically with an amplitude of 50 pixels and a frequency controlled by dividing the x-coordinate by 50. The visualization uses the Canvas API's `getContext('2d')` method and `lineTo()` function to plot each point incrementally, advancing horizontally by 2 pixels per iteration. A goldenrod border frames the canvas, while the wave itself is rendered with the default black stroke. No external libraries are used; the implementation relies purely on native JavaScript and the HTML5 Canvas API.
