This example renders a stylized smiley face using React and D3. The face is composed of a gold circle with a black stroke, two black eye circles, and a black mouth created from a D3 arc path. The drawing is centered using a D3 arc generator for the mouth and React’s SVG element construction. All coordinates and dimensions are calculated from the canvas width and height variables, and the entire face is grouped and translated to the center of the 960×500 SVG canvas.
