This dendrogram visualizes a career-path hierarchy, showing the relationships from a central "Career Root" through three main domains (Technology, Healthcare, and Creative) to specific job roles. Each node is a colored circle, with branches colored by category (steelblue for Technology, tomato for Healthcare, green for Creative). The example uses the D3 v7 `d3.stratify` and `d3.tree` layout functions to compute the tree structure and positions, rendering 1300x400 coordinate space onto an SVG. Node and link drawing relies on `root.links()` and `root.descendants()` to populate the SVG elements.
