The Hub Overview diagram provides a visual overview of the existing entities, grouped into categories.

The following image shows a sample Hub Overview diagram:

When you hover over an entity in the diagram, all related entities are highlighted. For example, when you hover over a topic, the applications and the publications that publish to the topic and the subscriptions that subscribe to the topic are highlighted. When you click an entity, a drill down view of the entity and its relations to other entities appears. For example, when you click a publication, the drill down view shows the publishing application, the topic to which the publication publishes data, and the subscriptions that subscribe to the topic. Click any entity in the drill down view. The edit window of the selected entity displays.
