A yellow smiley face is drawn on an SVG canvas using D3.js v5, with two black eyes and an arc-based mouth positioned relative to the center of the 960x500 viewport. The code explicitly sets circle radii, coordinates, and fill/stroke attributes, while the mouth uses the d3.arc() helper to generate a path with defined inner and outer radii and angle ranges. Static geometric values define the face’s proportions, with no dynamic data or interaction involved.
