This example shows a bare minimum HTML page that renders a heading and an SVG circle, using the browser’s native Document Object Model and `<svg>` element without any JavaScript libraries. The SVG contains a single `<circle>` element with a radius of 50 units but no positioning or styling attributes, leaving it in default coordinates. The page demonstrates the simplest possible structure for embedding vector graphics in HTML, with the rendering handled directly by the browser’s SVG engine. The example serves as a starting point for more complex visualizations, using only static markup and no external data or interaction.
