{"version":"1.0","type":"rich","title":"Transforming Data","description":"This example demonstrates data transformation by loading the Iris flower dataset from a CSV file and computing the average sepal length for each species. The code uses D3 v7 APIs including `csvParse`, `flatRollup`, and `sum` to process the data, then displays the resulting summary as formatted JSON text in a `<pre>` element. It showcases D3’s data-loading and aggregation capabilities, along with ES6 module imports for modular code organization. The visualization updates dynamically when data is fetched asynchronously.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/49b7dbfa893c44b9bfd23515f0f4a148?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
