This example visualizes a family tree as a static SVG diagram, with nodes rendered as orange circles connected by maroon lines. The tree structure is defined by parent-child relationships in a JavaScript array, which is processed using d3.stratify and d3.tree to compute node positions. The React-based code appends SVG elements using d3.select and animates the appearance of links and text labels with d3.transition and duration timings. Each node displays a name in blue text, and the visualization starts with root node "Dom" at the top.
