This interactive family tree visualizes hierarchical relationships using nested nodes and connecting links, with each person represented as a colored rectangle labeled by name and type. The tree expands and collapses on click, and supports pan and zoom via mouse interactions, while tooltips display additional link information. Built with D3.js v3 and React, the SVG-based animation uses the `d3.layout.tree` algorithm to position nodes and `d3.behavior.zoom` for navigation, with data loaded from a JSON file defining the family structure.
