This tree visualization displays a family hierarchy with the root “alboyes” branching into two primary children, each with their own descendants. The data is loaded from a JSON file using `d3.json`, and the layout is computed with `d3.tree` and `d3.hierarchy`. Nodes are rendered as styled text elements with colors from the data (e.g., blue, red, black), connected by horizontal links generated via `d3.linkHorizontal`. The entire SVG renders with `d3.zoom` support, allowing interactive pan and zoom.
