{"version":"1.0","type":"rich","title":"loadDataState","description":"This example shows how React state manages the lifecycle of data loaded with D3. It displays a summary message (row and column counts) from a CSV file containing CSS named colors. The code uses React hooks (`useState`, `useEffect`) to fetch data asynchronously with `d3.csv` and store it in state. A loading indicator appears until the promise resolves, then the `message` utility formats the dataset’s dimensions for display.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/91dcbc14b806470a8772c28cdf319be3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
