This example showcases a minimal SVG drawing of a smiley face, composed of a large yellow circle with two smaller black circles for eyes. The code relies entirely on the HTML5 `<svg>` element and its associated shape tags, such as `<circle>`, to define the graphic. The page uses an inline `<style>` block to remove margins and hide overflow, ensuring the visualization fills the viewport without scrollbars. The rendering approach is direct SVG markup, with no JavaScript libraries like D3 or external data sources involved.
