This example shows a hierarchical tree of a university department structure, with colored nodes connected by curved links. The layout is computed using D3’s `d3.stratify` and `d3.tree` APIs, which organize the data into parent-child relationships and positions nodes in a tidy tree. Node positions are rendered as SVG circle and text elements, while links are drawn as cubic Bézier paths using template literals. Data is loaded remotely from a CSV file via `d3.csv`, and all rendering uses the D3 v7 library.
