This example renders a yellow smiley face in an SVG canvas using React for component structure and D3’s `arc` function to draw the mouth. The face consists of a large yellow circle with a black stroke, two dark eyes positioned symmetrically, and a semicircular mouth path generated from an arc with a 90-degree angle. The code uses ReactDOM to mount the component, while D3 v7 supplies the arc generator, and all shapes are drawn as SVG elements with fixed pixel coordinates. The visualization demonstrates a minimal, static composition without interaction or data binding.
