This visualization presents a family tree using an animated node-link diagram. The tree is built from a flat dataset of parent-child relationships, processed by the `d3.stratify()` and `d3.tree()` utilities, and rendered as SVG circles and paths. Green nodes, representing individuals, connect via lime-colored links that draw themselves over one second, while the node radius animates in. Text labels appear inside each circle using `d3.select('g')` and `transition.attr`, mapping child names to positions derived from the tree layout.
