This example shows a single SVG circle rendered without any visible text or labels on a blank canvas, set against a full-window hidden-overflow background. The circle uses no positioning attributes, so it defaults to the top-left corner of the 960×540 SVG, appearing as a basic geometric shape. The code uses an inline SVG element directly in HTML, not d3 or other libraries, relying solely on native SVG circle syntax. The page also embeds a YouTube video iframe, though it is not part of the displayed visualization. Rendering is static, with no interaction or animation.
