n8n Workflow Dependency Graph with Auto-Tagging

This n8n workflow automates the analysis of workflow dependencies within an n8n instance. It identifies which workflows call others, builds a visual dependency graph, and automatically tags subworkflows based on their relationships. The workflow fetches all workflows, constructs a graph of calling relationships, filters relevant sub-workflows, and generates a visual pie chart to depict the most frequently called workflows. Additionally, it updates tags in the n8n system, facilitating better organization, documentation, and maintenance of complex automation setups.
