Smile
A yellow circle with a thick black outline forms a smiling face, complete with two black eyes and a curved arc for the mouth. The face is centered in an SVG canvas and rendered using React components. The code imports React and ReactDOM to create SVG elements, while D3 is loaded but its arc generator is commented out, leaving the smile drawn as a static path. The visualization relies on basic SVG shapes within a React-rendered `<svg>` element.
