{"version":"1.0","type":"rich","title":"practice","description":"This example demonstrates a minimal React application that renders a static text message. The interface displays the phrase “Hello React!” centered on a white background. The implementation relies on the `createRoot` API from `react-dom` to mount an `App` component, which is defined with JSX and a CSS class for styling. The code imports React and uses the UMD builds of React 18.2.0 and ReactDOM, loaded via a CDN, to bootstrap the root element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cfa17a8ab8e744c29282a3f2fc468522?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
