Hello HTML
A bare-bones HTML document renders a single yellow circle with a black outline on an empty SVG canvas. The page relies solely on intrinsic SVG elements—no external JavaScript libraries or data sources are involved. The circle is centered via fixed `cx` and `cy` attributes, sized with a `r` of 100, and styled through explicit `fill` and `stroke` presentation attributes. The SVG is embedded directly in the body with inline dimensions of 960 by 500 pixels, and the page includes a minimal CSS rule that removes margins and hides overflow.
