Which element is NOT part of the hierarchical composition of an Insight App?

The correct answer highlights that external APIs are not part of the hierarchical composition of an Insight App. Insight Apps are designed to provide business intelligence through a structured framework that typically includes dashboards, data models, and data products.

Dashboards serve as the visual interface for users to interact with insights. They compile data representations that help in decision-making. Data models define the structure and organization of data, facilitating the retrieval and representation of information effectively. Data products are the end result of processing data, representing valuable analyses or algorithms that users can leverage for insights.

In contrast, external APIs act as connectors that allow applications to communicate with other systems or services but do not constitute a hierarchy within the Insight App's internal structure. They are used to fetch data or functionalities from outside sources, thereby serving a supportive role rather than being a core component of the Insight App's hierarchy. This distinction clearly sets external APIs apart from the other elements that are foundational to the Insight App's architecture.
