{"version":"1.0","type":"rich","title":"Transforming Data","description":"This visualization displays the average sepal length for each iris species in the Fisher Iris dataset, computed from the raw measurements in data.csv. The code first parses the CSV with `d3.csvParse`, converts numeric fields, then uses `d3.flatRollup` and `d3.sum` to aggregate the data by species, calculating the mean sepal length per group. The result is rendered as formatted JSON text in a `<pre>` element, with the data loading process managed through a simple state machine and `fetch` to retrieve the CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/78610af17f4d4f7b9c498e209e58d800?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
