This smiley face is a simple data visualization built as a React component, rendered as an SVG. It displays a yellow circle with a black outline, two eyes, and a mouth arc. The code uses React for the component structure and `d3.arc` from D3 v5 to generate the mouth path. The SVG is defined with a fixed width and height, and the face is centered using a transform. All shapes are drawn with basic SVG elements—circles for the face and eyes, and a path for the mouth.
