This example shows a simple smiley face built from three SVG circles on a yellow background, with two smaller circles representing eyes. The face is drawn using the SVG `<circle>` element, with the main face circle filled in yellow and outlined with a black stroke. The eyes are positioned using explicit `cx` and `cy` coordinates within an SVG canvas. The code relies solely on the HTML5 SVG API and does not use any JavaScript libraries or D3.js functions for rendering or interaction.
