{"version":"1.0","type":"rich","title":"Transforming Data","description":"This example loads the classic Iris flower dataset from a local CSV file and uses D3.js version 7. The visualization demonstrates data transformation by grouping measurements by species and calculating the average sepal length for each group using `d3.flatRollup` and `d3.sum`. The result is rendered as a formatted JSON object inside a `<pre>` element, showing the computed summary statistics. The code also illustrates asynchronous data loading via `fetch()` and uses `d3.csvParse` to convert the CSV text into structured data, while showcasing D3's `select` API for DOM manipulation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3f9a2b39cf28474eb89fc5f60d60d59a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
