{"version":"1.0","type":"rich","title":"Activity 7.1 Question 1","description":"This example shows a pie chart of product sales aggregated by category, with animated slices that grow into place using a transition. It uses D3.js v7 to load data from a CSV file hosted on GitHub Gist, aggregate sales with `d3.rollup`, and generate pie slices via `d3.pie` and `d3.arc`. Labels are placed outside the slices with connecting polylines, and a legend is appended. The animation relies on `transition.attrTween` with an interpolated arc.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ee674da0f4024faa8163d6a28eda99fa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
