This gallery example shows a stylized smiley face built from basic SVG shapes: two eyes, a curved mouth, and a large background circle. The face is centered on a 960-by-500 canvas, with the background filled by a red-to-blue radial gradient. The visualization is implemented as a React component, using D3’s `arc` API to generate the mouth path. The code also uses ReactDOM to render the SVG into a root div, with styles applied directly in the HTML file.
