This example shows a family tree of named characters, with circular nodes connected by animated straight-line links. The layout is computed using `d3.stratify()` to build a hierarchy from parent-child data and `d3.tree()` to position nodes. The SVG rendering uses `d3.select`, and node circles and text are appended with transitions that animate their appearance. Links are drawn as path elements that animate from the source to the target position. The data is a static array of ten entries, and the visualization uses d3 v6 with a light blue background and orange nodes.
