A bare-bones HTML page renders a single SVG circle with no axes or labels, demonstrating that any valid HTML document can serve as a visualization container. The circle’s radius is set to 100 via the `r` attribute, while the `<svg>` element defines the drawing area. No JavaScript libraries or data sources are used; the example relies purely on static markup within the page’s `<body>`. This highlights the minimal structure required to begin building chart or diagram primitives.
