This animated visualization demonstrates a sine wave traveling across an HTML5 Canvas, with a horizontal center reference line and adjustable wave parameters for amplitude, frequency, and speed. The code uses the Canvas API’s `getContext('2d')` for drawing, `requestAnimationFrame` for smooth animation, and `addEventListener` with the window resize event to maintain a responsive canvas. The wave’s phase updates each frame, creating the motion effect against a white background with a subtle border and shadow.
