This example displays a single yellow circle centered on a 960-by-500 SVG canvas, outlined with a thick black stroke. The page is a minimal HTML document with a full-bleed body style and hidden scrollbars. It uses inline SVG markup within the HTML, directly defining the circle element with explicit `fill`, `stroke`, and `stroke-width` attributes, and does not employ any external JavaScript or visualization libraries. The data is static and hard-coded into the markup.
