This example shows a static SVG circle centered at the top-left of the viewport, demonstrating the basic structure of an HTML page that combines CSS styling and JavaScript. The page includes a single `<svg>` element containing a `<circle>` with explicit `cx`, `cy`, and `r` attributes, while a CSS rule styles a `.message` class with a large font size and centered text alignment. The rendering uses raw SVG markup directly in the HTML, with no external libraries or frameworks beyond the standard document structure. The code serves as a minimal template for building interactive visualizations, as referenced by the accompanying React starter.
