{"version":"1.0","type":"rich","title":"Transforming Data","description":"This example loads the Iris flower dataset from a CSV file and computes the average sepal length for each species using `d3.flatRollup` and `d3.sum`. The result is displayed as a JSON-formatted text summary on the page. D3’s `csvParse` handles data loading, and numeric fields are explicitly converted to numbers. The visualization updates through React-style state management, with a loading placeholder shown before the fetch completes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f2374a30f89f4ea98e266b8219d919f6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
