This example shows a family tree diagram rendered as an animated SVG, with nodes representing characters and lime-green paths linking parents to children. The tree data is processed using `d3.stratify` and laid out via `d3.tree`. Circles and text labels are appended to a group, while each link path animates from its source to target position using `transition()`. The visualization uses D3 v6, applies a black background, and assigns light green, lime-stroked circles to each node.
