{"version":"1.0","type":"rich","title":"Transforming Data","description":"This example displays the average sepal length for each iris species, computed from the classic Iris dataset. It presents the result as a formatted JSON object rendered in a `<pre>` element, showing a concise text-based summary rather than a graphical chart. The visualization loads the `data.csv` file via `fetch`, parses it with `d3.csvParse`, and converts numeric string fields to numbers. It then uses `d3.flatRollup` with `d3.sum` to calculate the mean sepal length per species, and `d3.select` to update the DOM with the resulting summary.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e26dbef802f846a986a709101f5201bb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
