This visualization shows a hierarchical tree representing a student’s academic structure, with root, course, and name branches extending to grades and individual name components. Each generation is color-coded by depth, and animated paths draw connections between nodes. Built with D3 v6, it uses `d3.stratify()` to convert flat parent-child data into a hierarchy, `d3.tree()` for layout, and SVG transitions with `transition().duration()` to animate the links and node radii.
