This example shows a React-based dropdown menu that lets users choose between demographic categories labeled “total,” “male,” and “female,” though the selection currently only updates a console log and does not alter any visible chart. The interface uses React’s `useState` hook to manage the selected value and a custom `Dropdown` component to render an HTML `<select>` element with options derived from a static array. The page is structured with index.html, an empty SVG placeholder, and React production scripts loaded via CDN, while Bootstrap is not used; styling is minimal and inline.
