This example shows a hierarchical tree of mobile phone brands, styled as a family tree with colored nodes and labeled connections. It uses D3 v5’s `d3.stratify` to convert flat parent-child data into a hierarchy, then `d3.tree` to compute node positions. The SVG renders circles for nodes, curved paths for links, and text labels, with node colors determined by depth level. The embedded YouTube video likely documents the original ICE 8 project, though the code itself runs independently.
