This example uses React with D3.js to draw a stylized smiley face in SVG. It shows a yellow circle with a black outline, two black eye circles, a curved smile drawn as an arc, and a straight line for a nose. The code constructs the shapes using D3’s `arc()` and `line()` generators, while React renders the SVG elements. The face is centered via a transform, and all dimensions and positions are defined with constant values, producing a static illustration without interaction.
