{"version":"1.0","type":"rich","title":"Activity6_4_Transforming the Data","description":"This example demonstrates how to transform the Iris flower dataset by computing the average sepal length for each species using D3's `flatRollup` and `sum` functions. The resulting summary is displayed as a JSON-formatted text block via `select`, `data`, and `join`. The visualization loads CSV data with `csvParse`, coerces numeric fields, and uses local ES6 modules alongside D3 v7 loaded from UNPKG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5ebf14a5c000496b9ff2b9042a4bc48e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
