This example renders a simple smiley face using SVG elements defined directly in HTML. It draws a yellow circle with a black stroke for the head and two smaller black circles for the eyes, with no mouth shown in the code. The visualization demonstrates basic SVG shape creation without any JavaScript or D3.js libraries, relying solely on hardcoded coordinates and styling within the markup. The SVG canvas is set to 960 by 500 pixels with a responsive layout that hides page overflow.
