explain how to read the page

The above diagram shows the color scheme of the layout in the main result page. The parent entities and officers who have significant controls over the individuals in focus are always inapplicable. The offspring entities and appointments are those entities that the individuals in focus can influence on.

Clicking the links on parent entities or officers, and offspring entities or managed companies will put them in focus and show upstream or downstream connections. In general, ascendant entities can be found by moving toward upstream, and descendant entities are by toward downstream. In this way, progenitor entities such as grandparent companies (parents of parent), sibling companies (children of parent), partner companies (parents of child), and progeny entities such as grandchild companies (children of child) can be found easily.
