This example draws a yellow smiley face on a blank canvas. It shows a large circular head, two smaller black eyes, and uses inline SVG elements in an HTML file. The code sets up an SVG container with specific width and height, then uses `<circle>` elements with fixed `cx` and `cy` coordinates to position the face parts. It does not use any JavaScript libraries or external APIs, relying instead on static SVG markup and CSS styling for the rendering.
