This example shows a simple yellow smiley face created with two black circular eyes on a yellow circular head, all centered on a white background. The graphic is rendered using SVG primitives within an HTML page, where each circle is defined by explicit `cx`, `cy`, and `r` attributes. The styling is handled through inline SVG attributes and accompanying CSS that controls the page layout and font sizing. The concrete APIs used are the SVG elements `circle` and the `svg` container, along with CSS properties for margin and overflow, demonstrating a static, framework-free visual composition. The code does not include any interactive behavior or dynamic data.
