This example shows a dropdown menu listing Pokémon names from the PokéAPI, which users can select to see their choice displayed. The React app fetches data from `https://pokeapi.co/api/v2/pokemon?limit=200` using `d3.json`, then passes the names to a `ReactDropdown` component. The selected value updates component state via `useState`, while the charting capabilities of Chart.js are loaded but not actively used in the displayed visualization.
