Hello HTML
This example shows a minimal HTML page that renders a single SVG circle with no additional styling or interaction. The page consists of a basic document structure with an `<svg>` element containing a `<circle>` of radius 100, which is drawn using the browser’s built-in SVG support. The example demonstrates how HTML and SVG can be combined in a standalone file without any external libraries or JavaScript, serving as a starting point for more complex visualizations. The code relies solely on native SVG rendering capabilities.
