Tree and List Views
Within each of the classes, properties and individuals tabs, you can toggle between two visualisation modes (the only exception is individuals, which only has a list view).
Tree View
It displays the ontology hierarchy as an expandable tree structure, showing parent-child relationships with the number of subclasses in parentheses. For example, in the classes tab, you can see “anatomical entity (16,344),” which expands to show terms like “anterior sector of right lobe of liver,” “immaterial anatomical entity (650),” and further nested terms.

List View
It presents the ontology terms in a flat list format for easier browsing and scanning. It also gives you the option to search.
