{"version":"1.0","type":"rich","title":"Activity6","description":"This example uses the D3.js v5 library to load, parse, and display a summary of the Iris dataset. The visualization fetches a CSV file, converts it to an array of objects, and uses a `flatRollup` operation with a `sum` reduction to compute the average sepal length per species, presenting the result as formatted JSON text in a `<pre>` element. The SVG and WebGL rendering in the index.html file is generated by external tools, not by the JavaScript code itself.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/388c53b4e35a407da17b75a4cdf093ae?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
