{"version":"1.0","type":"rich","title":"ACT(6) Task4","description":"This example loads the classic Iris dataset from a CSV file and displays the average sepal length for each species as a formatted text summary. It uses `d3.csvParse` to parse the data, `d3.flatRollup` to group by species, and `d3.sum` to calculate the mean. The visualization renders the result in a `<pre>` element, updating via a state management pattern that fetches and processes the data asynchronously. It demonstrates data loading, transformation, and simple text output using D3 v7.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/29ec9bf68fe84ef1a785d6fc2b5b5eba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
