{"version":"1.0","type":"rich","title":"Transforming Data","description":"The visualization demonstrates how D3 data transformation APIs can reshape the Iris dataset, computing the average sepal length for each species via `flatRollup` and `sum`. After fetching the CSV with `fetch()`, the data is parsed with `csvParse` and converted to numeric types. Results are displayed as formatted JSON in a `<pre>` element, showing a concise summary of the aggregated values. The example highlights the use of `flatRollup` and `sum` from the D3 API to perform binned aggregation and group operations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cf559232f33e4e0fa9f9d2ec7509c6d3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
