They often use the Execute Workflow node to pass data and control execution flow.\n2. **Sub-workflow**: A sub-workflow is any workflow that is executed by another workflow. These are often used for reusable automation logic, breaking down complex workflows into modular components.\n3. **Dependency Graph**: A dependency graph visually represents the relationships between workflows in an n8n instance. It maps out which workflows call others, helping users understand execution dependencies, optimize workflow organization, and prevent unintended changes that may break subworkflows."

It identifies which workflows call others ([sub-workflows](https://docs.n8n.io/flow-logic/subworkflows/)), builds a dependency graph, and automatically tags subworkflows with their calling workflows. This makes it easier to track dependencies, optimize workflow structures, and maintain documentation in complex n8n environments."
