{"version":"1.0","type":"rich","title":"Fork of Mouse Follower","description":"This example displays a minimal text summary of a COVID-19 deaths dataset. The React component fetches a CSV file from the Johns Hopkins CSSEGISandData repository and uses D3’s `csv` function to parse it. The resulting `data` object is passed to a custom `message` function, which computes and renders the file size in kilobytes, row count, and column count. The output updates dynamically through React’s `useState` and `useEffect` hooks, initially showing a “loading…” placeholder. D3’s `csvFormat` is used to measure the file size.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/20288e910cf948ffa10a9fb312b6fb1f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
