This interactive donut chart displays the distribution of student enrollment across ten prominent universities, with each slice labeled and color-coded. Hovering over a slice reveals the percentage of total students it represents via a tooltip. The visualization uses D3 v5 APIs including `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` with a custom color range from `d3-scale-chromatic`, while rendering SVG elements and tooltip interactions are managed through D3 selections. Data is loaded from a CSV file.
