{"version":"1.0","type":"rich","title":"assignment2","description":"This visualization is a pie chart that displays the distribution of student groups for individuals with math scores greater than 70. The chart uses a categorical color scale to distinguish groups, with labels showing the group name and count on each slice, plus a legend on the right. It loads exam data from a CSV file via `d3.csv`, filters rows by the math score condition, and aggregates counts using `d3.rollup`. The chart is rendered with SVG paths generated by `d3.pie` and `d3.arc`, using `d3.scaleOrdinal` with `schemeCategory10` for coloring.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d47cc32ef22146339832969f5ca784cd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
