# Topology The Topology is a rich UI that enables the visualization of detailed Data Flow Graphs, ETL Pipelines Stream Processing and Analytics workflows and their relation to native Lenses/Kafka resources, such as Kafka Topics, SQL Processors, and Kafka Connectors. The Graph in Lenses Topology is automatically generated based on the available applications running against your cluster. Lenses Topology is comprised of several different Nodes Types. From Topics, SQL Processors, and Connectors, to External Application. Each Node on the UI is clickable. That way, we can take a close view and look for more information regarding each Node. You can link any custom microservice or other streaming application running and producing, consuming, or processing data in Kafka by self-registering the application. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
