A single yellow circle with a thick black outline is drawn at the center of an SVG canvas. The example illustrates the minimal structure of an HTML page embedding SVG directly, with the circle positioned at coordinates (480, 250) and a radius of 200 pixels. The code uses standard HTML and inline SVG, with CSS to remove page margins and hide overflow. No external libraries or data sources are involved; the rendering is entirely self-contained within the `index.html` file.
