This example demonstrates a simple interactive menu system built with React and D3 v6, allowing users to select between two animal options—goldfish and cat. The interface displays a large label and dropdown select element, where changing the selection updates the component state and logs the chosen value to the console. The app uses React’s `useState` hook to manage the selected value and passes it to a reusable `Dropdown` component, which renders the native HTML `<select>` and `<option>` elements. The styling uses CSS to increase the font size of the label and select for better visibility.
