{"version":"1.0","type":"rich","title":"React Starter","description":"This example displays a full-screen message reading “Hello React!” in large, centered text. It demonstrates a minimal React application setup using React 16.13.1 and ReactDOM. The code defines a simple functional component, `App`, and renders it into the `root` DOM element via `ReactDOM.render`. The page relies on CDN-loaded React and ReactDOM production builds, with styling applied through a CSS class in the HTML file. No data or interactive visualization is present; it serves purely as a starter template for integrating React into an Observable-style gallery environment.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0e103d1e0b5b4b5e8011e1621f351c0d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
