This visualization presents a hierarchical sunburst chart of student enrollment data across Teesside University’s departments, courses, and modules, broken down by gender. It uses `d3.partition` to compute the layout and `d3.arc` for rendering SVG path segments, with animated zooming via click interactions and `transition` updates. The data comes from three JSON files (department names, pathways, and course modules), which are loaded using `Promise.all` and `d3.json`, and colored with a `d3.scaleOrdinal` interpolated rainbow scale based on department hierarchy.

Read in JSON department files

This visualization shows a hierarchical sunburst chart of module enrollments across Teesside University’s departments, courses, and modules, with male and female student counts as leaf values. A set of radio buttons lets the user filter the view to focus on specific departments (CAM, CSIS, GAV) or show all. The code loads three JSON files via `Promise.all` and `d3.json`—department names, course-to-department mappings, and module enrollments—then builds a hierarchical data structure. It uses `d3.hierarchy` and `d3.partition` to compute the sunburst layout, with `d3.arc` for the arcs, `d3.scaleOrdinal` with `d3.quantize` and `d3.interpolateRainbow` for coloring, and renders as an animated SVG with clickable segments.

Read in JSON department files

This visualization shows the enrollment distribution of male and female students across courses and modules within academic departments at Teesside University. Users can filter the view by department using radio buttons for All, CAM, CSIS, or GAV. The data is loaded from three JSON files using `Promise.all` and `d3.json`, then structured into a hierarchy. A sunburst layout, rendered with SVG paths via `d3.partition` and `d3.arc`, displays the data, with clickable segments and animated transitions on filter change using `d3.v5`.

Read in JSON department files

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.

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.

This example presents a zoomable sunburst visualization of Teesside University’s academic structure, showing departments, their courses, and course modules as nested arcs. It loads three JSON files—department names, pathways to departments, and course modules—and merges them into a hierarchical tree. Using d3.partition and d3.arc, the sunburst lays out nodes by angle and radius, while d3.hierarchy computes the layout from the aggregated data. Clicking arcs triggers a zoom transition via transition.attrTween, re-scaling the visualization around the selected node. The view applies a rainbow color scale to top-level departments and renders labels with conditional visibility.
