A minimal HTML page demonstrates an SVG circle with no visible attributes beyond a radius of 100 pixels, leaving it centered at the origin of the SVG viewport. The page contains no JavaScript or styling, only the raw `circle` element inside an `svg` tag. The example highlights a basic, unstyled SVG shape rendered directly in the browser, with no data loading or interaction. This fork of the "Hello HTML" template serves as a starting point for SVG visualizations.
