This example demonstrates a simple interactive dropdown menu for selecting a pet type, where the current selection is logged to the console. The interface displays a large label and select element, with six pet options (e.g., Goldfish, Cat, Dog) defined as an array of objects. Built with React and ReactDOM, the component `Dropdown` maps over the options to render `<option>` elements, using `useState` to manage the selected value and an `onChange` handler to update it. The styling is applied via plain CSS in the HTML, with no D3 APIs used in this visualization.
