This example shows a simple SVG scene with a yellow circle and two smaller black circles, arranged to resemble a face. The code uses raw HTML, CSS, and JavaScript within a single `index.html` file, with no external libraries. It demonstrates basic SVG rendering by drawing three `<circle>` elements inside an `<svg>` container sized at 960 by 500 pixels. The CSS in the `<style>` block removes the page margin and hides overflow, while the circles are positioned using explicit `cx`, `cy`, and `r` attributes with hardcoded fill and stroke values.
