Big smiley face
The Big smiley face example displays a single, large circular face rendered as a smiley in a minimalist SVG layout. The visualization shows only the basic geometric shape without additional data or interactive elements. The code uses the SVG `<circle>` element within an HTML page, relying on native browser rendering rather than external libraries or JavaScript APIs. The page structure includes a bare minimum HTML document with an embedded `<svg>` tag, and the face itself is empty and unadorned, with no styling or attributes applied.
