This example demonstrates a pet selection interface using a React dropdown menu. It presents six animal options—dog, cat, hamster, parrot, spider, and goldfish—with the cat option preselected as the initial value. The visualization shows how React manages state through the `useState` hook, updating the displayed selection when the user chooses a different animal. The code uses React 17 and ReactDOM to render the component, while the dropdown itself is built with standard HTML `<select>` and `<option>` elements. The interaction pattern highlights state management in a React-based data visualization context.
