This example shows a minimal HTML page that combines CSS and JavaScript to render a styled greeting and a simple SVG shape. The page uses inline CSS to format a centered message at a large font size, and directly embeds an SVG element containing a single circle. The SVG circle is defined with explicit `cx`, `cy`, and `r` attributes, demonstrating basic vector graphics markup within an HTML document. The JavaScript is not used for dynamic behavior, but the structure provides a bare-bones starter for building interactive visualizations with modular web technologies.
