{"version":"1.0","type":"rich","title":"Loading Data","description":"This example demonstrates asynchronous data loading with D3 and React. It fetches a CSV file of CSS named colors from a GitHub gist, then displays the file size, row count, and column count as plain text. The code uses React hooks (`useState`, `useEffect`) to manage state and trigger the `d3.csv` request, while a helper function formats the statistics from the parsed data. Rendering switches from a “loading…” message to the dataset summary once the promise resolves.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
