This interactive family tree displays the descendants of Simon in a hierarchical layout. The visualization uses color-coded nodes, with black for the root, red for direct children, and green for grandchildren, connected by curved paths. Built with D3.js v5, it employs the `d3.stratify` and `d3.tree` APIs to compute node positions and links from an array of parent-child pairs. The SVG rendering includes labeled text for each family member, with the graph sized at 800 by 650 pixels.
