{"version":"1.0","type":"rich","title":"tsk","description":"This example loads the classic Iris flower dataset from a CSV file and computes the average sepal length for each species using d3.flatRollup and d3.sum. The resulting summary is rendered as JSON text in a pre element, demonstrating asynchronous data loading with fetch, parsing with d3.csvParse, and state management through a simple setState pattern. The visualization is built with d3.v7 and local ES6 modules.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/56539ea2d07a44ed995de373fe98b0d6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
