{"version":"1.0","type":"rich","title":"assignment","description":"This pie chart visualizes the pass/fail distribution of students from a performance dataset. The D3.js code (using `d3.pie`, `d3.arc`, and `d3.rollup`) aggregates the `pass_fail` column into slice counts, with each slice labeled as a category and its percentage. A right-side legend, built with `d3.select` and dynamic HTML joins, lists each category and its raw value. The SVG rendering uses ordinal colors from `d3.schemeTableau10` and includes slice borders and white text strokes for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/593c09ccd95d445592550148a1dc536c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
