This example shows a simple smiley face constructed from four SVG circles: a large yellow head with a black outline, and two smaller black circles for eyes. The code uses basic SVG elements within an HTML page, setting coordinates and styling attributes directly on each `<circle>` element. The head is centered at (480, 250) with radius 245, while the eyes are positioned symmetrically at (380, 200) and (580, 200) with radius 50. All shapes are rendered using SVG’s built-in rendering, with no external libraries or data sources.
