Hello HTML
This example displays a single yellow circle centered on a 960 by 500 SVG canvas, demonstrating a minimal HTML page that renders a static vector graphic. The code uses a plain HTML `<svg>` element with a `<circle>` shape, setting its `cx`, `cy`, `r`, and `fill` attributes directly in the markup. It does not employ any JavaScript libraries or data sources, relying solely on static SVG markup. The page’s body removes margins and hides overflow, making the shape fill the viewport with the specified dimensions.
