This visualization presents a family tree as an interactive, animated diagram built with D3.js v3 and React. It shows hierarchical relationships between family members, using colored rectangles for different node types and connecting links with directional arrows. The tree layout is computed with `d3.layout.tree`, and nodes and links are rendered as SVG elements. The visualization supports zooming and dragging via `d3.behavior.zoom`, plus click interactions to expand and collapse nodes. Data is loaded from a JSON file and styled with custom CSS, with tooltips for additional information.
