A minimal SVG visualization renders a single large circle with no fill, centered within a 1000-by-500 viewport. The page uses inline SVG elements directly in HTML, with CSS resetting the body margin and hiding overflow. The circle’s radius is fixed at 200 pixels, but its center defaults to the SVG origin, placing it off-center. No scripting or external libraries are involved; the example demonstrates basic SVG markup and static styling within a bare HTML document.
