{"version":"1.0","type":"rich","title":"Pie Chart - AI Usage Distribution","description":"This pie chart visualizes the distribution of AI usage among students, showing the proportion who use AI compared to those who do not. The visualization loads a CSV dataset from a GitHub repository using `d3.csv`, filters incomplete records, and aggregates counts via `d3.rollup`. It renders slices with `d3.pie` and `d3.arc` in an SVG, applies an ordinal color scale, labels each segment with category and value, and includes a legend. The design uses purple shades and white-stroked arcs for clarity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/566f772201834d07922abb9d46f7bbf8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
