This example demonstrates a minimal HTML page that renders a simple SVG face using basic shapes—a yellow circle with black outlines for the head and eyes. It shows how to use CSS to reset page margins and hide overflow, ensuring the graphic occupies the full viewport. The code uses plain HTML, CSS, and JavaScript-free SVG elements, directly embedding a `<svg>` tag with two `<circle>` elements. This serves as a bare-bones starting point for more complex web visualizations, with no external libraries or data sources involved.
