{"version":"1.0","type":"rich","title":"Transforming Data","description":"This example summarizes the classic Iris flower dataset by grouping measurements by species and displaying the average sepal length for each in a simple preformatted text output. The visualization demonstrates D3.js data transformation workflows by loading a CSV file with `d3.csvParse`, converting string values to numbers, and then using `flatRollup` with `sum` to calculate group means. The resulting summary is rendered as JSON text in the page, showing how raw tabular data can be aggregated into concise, readable statistics.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fbdb3fcc8fff4c289546b69a3bddab48?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
