This example shows a hierarchical family tree rendered as a dendrogram, with nodes labeled by name and curved links connecting parents to children. The data is embedded as a CSV string and parsed with `d3.csvParse`, then converted into a hierarchy using `d3.stratify`. The layout is computed with the `d3.cluster` tree layout, and links are drawn as SVG paths using a custom `project` function that maps tree coordinates to screen positions. Text labels use varying font sizes based on node depth.
