This example shows a simple HTML dropdown menu for selecting a car model, built with React and D3. It renders a static select element with four car options (Volvo, Saab, Mercedes, Audi) using React’s `ReactDOM.render`. The code imports the `arc` function from d3, though it uses no D3 drawing or data-binding APIs in the visible logic. The example demonstrates minimal integration of React components with D3’s function imports, providing a basic interactive form control without additional visualization.
