{"version":"1.0","type":"rich","title":"Read in JSON department files","description":"This example shows a zoomable sunburst chart of student enrollment data by department, course, and module, with a breakdown of male and female students. A radio button selection allows users to choose a department for focus. The data is loaded from three JSON files using `Promise.all` with `d3.json`. The visualization uses D3 v5’s `d3.partition`, `d3.hierarchy`, and `d3.arc` to render the SVG-based radial layout, with click interactions to zoom and animate through the hierarchy. Colors are assigned via `d3.scaleOrdinal` with a rainbow interpolator.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/29211ad91d0d4b449d20cb1f398af0b1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
