A static vector illustration of a smiling face uses two concentric circles for the eyes and a larger outlined circle for the head, all rendered directly in SVG within an HTML page. The example relies on basic SVG elements—`circle`, `fill`, `stroke`, and `stroke-width`—to construct the face, with no JavaScript or external libraries. The yellow head and black eyes are positioned using explicit `cx` and `cy` attributes, and the page includes minimal CSS to remove body margins and prevent scrolling.
