This interactive family tree visualizes three generations of relationships using a hierarchical layout. Circles represent individuals, color-coded by generation (green, lightblue, yellow, red), with orange animated links connecting parents to children as they draw over time. The SVG is rendered with React and D3 v6, using `d3.stratify()` to structure the data and `d3.tree()` to compute positions. Node and text elements are bound via data joins, with CSS styling and transitions animating both path connections and circle radii.
