Vizceral is a visualization component for displaying flows between nodes in a nested set of graphs. Each graph has a set of nodes and connections to be rendered with flow metrics for each connection. Each node can also have it's own set of nodes and connections, allowing the user to 'drill into' each node to visualize another level deep of traffic information.
Netflix currently uses it with three levels: traffic requests into each AWS region, traffic between individual microservices within those regions, and lastly to specifically focus on traffic flowing into and out of a specific microservice.
