{"version":"1.0","type":"rich","title":"Read in JSON department files","description":"This interactive sunburst chart visualizes university enrollment data, showing student numbers (male and female) across different departments, courses, and modules. The hierarchical radial layout allows users to click on a department segment to zoom in and explore its specific course and module breakdowns. The visualization is built with D3.js v5, using the `d3.hierarchy`, `d3.partition`, and `d3.arc` APIs to construct and render the radial diagram. The code loads JSON data from three separate files—department names, pathways to departments, and course modules—and uses a promise-based `Promise.all` to load them asynchronously before constructing the hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b3e9880636bc4f8eb5b9ad2ffffcdf38?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
