This example uses React to create a minimal SVG visualization of a headlight beam projecting onto a wall and ground. It draws a blue vertical wall, a gray ground line, and a yellow circle representing the headlight, with green and red dashed lines simulating the light beams. The code constructs SVG elements directly via the DOM API (`document.createElementNS`) and appends them to the document body. The visualization is a static, hardcoded scene with fixed coordinates, sizes, and stroke styles, demonstrating basic SVG shape rendering without interactivity or data-driven input.
