A black-and-yellow smiling face rendered as a static SVG graphic using only native SVG elements (`circle` and `svg`) within an HTML page. The composition places a large yellow circle with a black stroke as the head, flanked by two smaller black circles for eyes. No JavaScript libraries or data sources are used; the markup is hand-written in `index.html` and styled with CSS to eliminate page margins. The example demonstrates basic SVG shape creation without interaction or animation.
