d3-hierarchy provides data structures for hierarchical data, such as a tree or dendrogram. It facilitates efficient traversal and manipulation, enabling calculations of node depths, breadths, and relationships. Essential for visualizing hierarchical data, d3-hierarchy is widely used to construct interactive and informative diagrams within the D3.js ecosystem. Key features include tree layouts, cluster layouts, and partition layouts.
