Fork of Hello HTML
A minimal SVG circle is centered on a blank 960-by-500 canvas with no axis, labels, or interaction. The page uses raw HTML with an inline `<svg>` element and a `<circle r="200">` tag, rendering via the browser’s SVG engine. The example demonstrates the simplest possible D3-free SVG structure, serving as a starting point for more complex visualizations. No JavaScript libraries or data sources are involved.
