{"version":"1.0","type":"rich","title":"Transforming Data","description":"A data-transformation example reads the classic Iris dataset from a CSV and computes the average sepal length per species using D3’s `flatRollup` and `sum` APIs. The result is rendered as a formatted JSON summary displayed inside a `<pre>` element, demonstrating the library’s data-wrangling capabilities. The code highlights loading D3 via UNPKG and the use of local ES6 modules alongside a state-management pattern for asynchronous data fetching.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a1a678bb487e400e9a6220897ac1f778?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
