Look at the pictures - Does this type of hierarchical list or table, where you start reading it from the left and the data become more and more narrow, have a common name?
There's no hierarchy in those diagrams.
Hierarchy or Visual Hierarchy is the order of the elements in the way that human eye perceives them or all the elements ranked in order of priority.
- Vertical arrangements: elements are sorted in order of rank, from largest to smallest, highest to lowest, and so on.
- Linear hierarchy: there is for each element a superior and a subordinate element, and the rank order results in a continuous sequence
The images at the question are a Classification Chart displayed as a table and a Table of contents.
