This example shows a simple, single circle rendered on a blank SVG canvas. The page relies on a minimal HTML structure with inline CSS to center the content and hide scrollbars, while the SVG element defines a fixed 960 by 500 pixel drawing area. The code uses the native SVG `<circle>` element with a large radius, though the circle has no position or fill attributes set. No JavaScript libraries or data sources are used; the rendering is purely declarative SVG within the HTML document.
