This example shows a simple smiling face built with SVG shapes, created using React and D3.js v7. The face consists of a blue circle with a red stroke, two yellow eyes, and a mouth drawn using D3’s `arc()` generator with specific start and end angles. The SVG is rendered dynamically via `ReactDOM.render()` into the `#root` element, with positions and sizes defined by variables for easy adjustment. No external data source is used; the visualization relies entirely on hardcoded parameters for its geometric composition.
