{"version":"1.0","type":"rich","title":"Loading Data with React D3","description":"This example demonstrates how to load external data into a React application using D3 utilities, displaying a summary message about the dataset after it is fetched. It asynchronously loads a CSV file via the `csv` method from d3.v5, storing the result in React state with the `useState` and `useEffect` hooks. The message, generated by a custom `message.js` function, reports the file size in kilobytes, row count, and column count using `d3.csvFormat` and properties like `data.length` and `data.columns`. While loading, the UI shows a placeholder text.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1ad5bf5b328941a58eb75e0374a92f46?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
