{"version":"1.0","type":"rich","title":"Question 1 - Pie Chart","description":"This pie chart displays the distribution of users across Android, iOS, and BlackBerry OS, with each slice labeled by its percentage share. The visualization uses D3 v6’s `pie`, `arc`, and `scaleOrdinal` APIs to generate the chart, while `csv` loads and aggregates the underlying data from a remote gist. Rendered as SVG, it also includes a legend and title, with slice labels positioned via `arcPath.centroid` and formatted using `d3.format`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ccd5d9a7a17b4289917cb262c31460ff?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
