Fork of Hello HTML?????
This example shows a classic smiley face rendered as an SVG using React for component structure and D3’s `arc` generator for the mouth. The face consists of a yellow circle with a black stroke, two black eyes positioned via fixed offsets, and an arc path drawn from a semicircular angle range. The code imports `arc` from D3 v5, uses JSX to define the SVG elements, and relies on React’s `ReactDOM.render` to mount the component. No external data is used; all shapes are hardcoded with absolute dimensions and positions.
