This example renders a simple, minimal SVG scene: a single circle with a radius of 200 pixels centered on a 960×500 canvas. The page uses no JavaScript libraries, relying instead on plain HTML and inline SVG markup. The body is styled with `margin: 0` and `overflow: hidden` to create a full-bleed viewing area, and the circle is drawn without an explicit fill or stroke, leaving its appearance to default browser styling. It demonstrates the fundamental structure of an SVG-based embedded visualization.
