This example demonstrates how a React component can integrate D3 to render dynamic content, showing a simple text message that updates via D3’s selection API. The code uses `useRef` to attach a DOM node, then `select` from D3 to set its text content within a `useEffect` hook. It relies on React’s `createRoot` for mounting and D3’s `select` method for direct DOM manipulation. The example serves as a minimal starter template for combining React’s stateful rendering with D3’s data-driven utilities.
