This example displays a single, large unfilled circle centered within an SVG canvas, using a minimal HTML page structure. The visualization relies on the SVG `circle` element rendered with a default black stroke and no fill, set against a white background. The page’s embedded styling removes margins and hides overflow, while the SVG’s fixed width and height define the drawing area. The code uses no external libraries, only native HTML and SVG APIs, with the circle’s radius set via the `r` attribute. The result is a stark, geometric composition demonstrating basic SVG markup without additional interaction or data binding.
