This example shows a minimal SVG visualization consisting of a single large circle centered on a 960×500 canvas. The circle is rendered using raw SVG markup with a radius of 200 pixels and no fill or stroke styling, making it nearly invisible against the white background. The implementation relies on inline CSS in the HTML head to set page margins and hide overflow, while the SVG element is embedded directly in the body. No JavaScript libraries or data sources are used, making it a bare-bones demonstration of basic HTML, CSS, and SVG structure.
