This example shows a minimal React application that renders a simple "App" div element. It serves as a basic starter template for visualizing data with React, demonstrating how to set up React 17 with ReactDOM. The code uses `ReactDom.render()` to mount the `App` component into the `#root` DOM element, while importing `React` and `ReactDom` directly. A placeholder `FaceWrapper` component is defined but not used. The page loads React via UMD scripts from unpkg and renders through the compiled `bundle.js` file.
