{"version":"1.0","type":"rich","title":"Untitled","description":"A donut chart displays the distribution of students across university majors, with each slice labeled by its proportion and a legend pairing colors to majors. The visualization loads course data from a CSV file via `d3.csv`, then uses `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to compute slice geometry and assign categorical colors from a fixed palette. Values are formatted with `d3.format` and rendered as text labels directly on the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4cccc6b2ed7d41318215aea8b3fec8dc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
