Hello HTML
A bare-bones HTML page renders a single yellow circle with a black outline, centered within an SVG canvas. The example demonstrates the simplest possible data-visualization setup, using an inline `<svg>` element with hard-coded coordinates and dimensions. The SVG `circle` element is styled through presentation attributes (`fill`, `stroke`, `stroke-width`), and the page’s CSS removes default body margins and hides overflow. The code relies solely on native HTML and SVG APIs, with no external JavaScript or data, illustrating a minimal static graphic.
