{"version":"1.0","type":"rich","title":"load data with d3 and update with react","description":"This example demonstrates a minimal React-based data loading flow, where a Web page displays either \"Loading...\" or \"yay\" based on whether asynchronous CSV data has been fetched. The React component uses `useState` to hold the loaded dataset and `useEffect` to call D3’s `csv()` method on a remote URL containing named CSS colors. Once the data arrives, React re-renders the paragraph, proving D3 and React can work together for data acquisition and UI updates. The page uses D3 v6 and React 16.9, with an SVG placeholder for a smiley face.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a797626c67b941babca76f4aaae11624?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
