Hello dumb
A simple SVG smiley face built with React and D3 v6 renders a yellow circle with a red stroke, two black and grey eyes, and a curved mouth created using the d3.arc path generator. The face is centered on a 960x480 canvas, with fixed positions for facial features. The example demonstrates embedding D3 shape utilities within a React component, using the arc’s inner and outer radii and start/end angles to define the mouth’s path.
