{"version":"1.0","type":"rich","title":"Read in JSON department files","description":"This interactive sunburst diagram visualizes student enrollment across university departments, courses, and modules, segmented by gender. The visualization aggregates three JSON data sources—department names, course pathways, and module records—into a hierarchical structure rendered as animated arcs. Using D3 v5’s `d3.partition` and `d3.arc`, the chart displays the hierarchy with color-coded segments for each department. Radio buttons allow filtering by department, triggering a transition that updates the displayed arcs. The code employs a `d3.hierarchy` with a `sum` accessor and a `d3.scaleOrdinal` with an interpolated rainbow color scheme.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ba563fa508454c8eb1317dab430f1442?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
