A single gray circle floats against a blank white background, centered in an SVG canvas. The example demonstrates the minimal structure needed to render a geometric shape using inline SVG markup, with the circle’s radius set to 200 units and no additional styling or interaction. The page includes only a basic HTML skeleton and an embedded iframe linking to a YouTube video, though the visualization itself relies solely on native SVG elements rather than any external libraries. A straightforward illustration of SVG’s core drawing capabilities.
