This example shows a social network family tree with ten nodes representing named individuals, connected by animated parent-child links. Using the d3.stratify() utility to build hierarchy from flat data, it renders the tree via d3.tree() with SVG circles and text labels. Path connections animate into place with transition().duration(), while nodes expand to a fixed radius size. The visualization employs d3.v6 and SVG elements on a light blue background, with every node styled with light yellow fill and green stroke.
