A simple SVG drawing depicts a face constructed from basic geometric shapes: a yellow circle for the head, two smaller black circles for eyes, and a red rounded rectangle for a mouth. The SVG markup uses standard SVG elements like `circle` and `rect` with explicit positioning and styling attributes, embedded directly in an HTML page with a grey background. No JavaScript libraries are used; the visualization relies purely on static SVG rendering within the browser, demonstrating how hand-coded vector shapes can form a recognizable character. The code does not include any data-driven or interactive features.
