A single SVG circle is the sole visual element, demonstrating a minimal HTML page structure. The page contains a 960x500 SVG element with a circle of radius 100, rendered without any styling or positioning attributes. The example serves as a bare-bones introduction to embedding SVG graphics directly within an HTML document, using standard markup with no external libraries or JavaScript. Its purpose is to show the simplest possible static data-viz setup where the rendered output is just an unstyled circle on a blank canvas.
