This visualization presents a four-generation family tree for the Stark family, with nodes colored by generation depth from blue to red. The graphic uses a vertical, top-down layout to show the hierarchical relationships between Eddard Stark and his descendants. Built with D3 v7, the code leverages the `d3.tree()` layout algorithm applied to hierarchical data via `d3.hierarchy()`, and renders edges using `d3.linkVertical()`. The SVG output uses circles for nodes and text labels for names, drawn through the `join()` operator.
