Shape with SVG and CSS
A large circle, rendered with SVG, fills the viewport against a plain white background. The example demonstrates the minimal structure needed to display a basic shape using an SVG `<circle>` element with a radius of 400, placed within a 960 by 500 viewBox. The page includes a linked stylesheet that hides scrollbars and defines a `.highlighted` class, though the circle itself receives no styling or interaction. The code uses no JavaScript libraries, relying solely on standard HTML, CSS, and inline SVG markup to produce the static visual.
