This example demonstrates a minimal SVG visualization that displays a single unfilled circle without coordinates or styling, centered within a 960-by-500 pixel canvas. The page, built as a React-compatible HTML file, uses inline CSS to remove margins and hide overflow. The SVG circle, defined with a radius of 200 pixels but no center position, renders at the origin by default, appearing in the top-left corner rather than the middle. The example relies on basic SVG circle elements and JavaScript through the enclosing HTML structure, with no additional data or dynamic behavior.
