This example shows a blank SVG canvas containing a single unfilled circle with a radius of 100 pixels, rendered directly in the HTML markup. It demonstrates the minimal structure of an HTML page that uses inline SVG for a simple vector graphic. The code relies on the native HTML `<circle>` element within an `<svg>` tag, with no JavaScript or external libraries involved. The page includes a title and uses plain CSS-compatible styling, serving as a bare-bones starter template for React-based visualizations in the VizHub environment.
