This fork of ICE-8 creates a family tree visualization using D3.js v5 and SVG rendering. The dendrogram layout uses a hierarchical data structure of family members, with circle size encoding a numeric value attribute and colored links and circles reflecting per-node category levels. Computed via d3.tree(), the tree positions nodes in a horizontal layout, while curved cubic bezier paths connect parents to children through custom link generation. Node styling applies both static CSS classes and dynamic inline style attributes for strokes and fills.
