Hierarchical Taxonomy Report

A Hierarchical Taxonomy Report is a taxonomy report that organizes information into a multi-level parent-child structure, showing how broad categories are progressively divided into more specific subcategories.

The hierarchy resembles a tree, where each level becomes more detailed than the level above it.

│   ├── Level 3 (Subcategory)
│   │   ├── Level 4 (Group)
│   │   │   └── Level 5 (Item)
