A single large yellow circle with a black outline sits centered in an SVG canvas, flanked by two smaller unfilled circles. The example demonstrates basic SVG shape rendering within an HTML page, using raw SVG elements like `circle` directly in the markup. The code sets a fixed canvas size of 960 by 500 pixels and applies CSS to remove default page margins. No JavaScript libraries or data sources are involved; the visualization is purely static vector graphics defined inline in the HTML.
