This visualization shows the hierarchical structure of a university, breaking down three colleges into nine departments and twenty-seven courses. It uses a vertical tree layout rendered as SVG through D3.js v7's `d3.tree()` and `d3.linkVertical()` APIs. Nodes are color-coded by depth, transitioning from red root to blue colleges, green departments, and yellow leaf courses. The static dataset is defined as a JavaScript object, with labels positioned above parent nodes and below leaves to improve readability.
