{"version":"1.0","type":"rich","title":"Transforming Data","description":"This visualization demonstrates how to use D3.js data transformation techniques to summarize the classic Iris flower dataset. It computes the average sepal length for each iris species using `d3.flatRollup` and `d3.sum`, then displays the resulting summary as formatted JSON text in a `<pre>` element. The code loads data from a local CSV file with `d3.csvParse` and showcases commented-out examples of other transformations like `d3.bin`, `d3.extent`, and `d3.group`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6a0173345ec544dcb4e38a8d6fc99960?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
