A yellow circle with two smaller black circles for eyes forms the first step toward a smiley face. The example uses React to render SVG shapes directly, with the outer face drawn as a single `circle` element and the eyes as additional circles, all positioned via explicit `cx` and `cy` coordinates. The chart includes a black stroke outline and yellow fill, with no interactive or data-driven behavior beyond static geometric composition. The code runs in a React root using `ReactDOM.render` and imports D3 v6, though no D3 functions are invoked.
