Feature: Rule Dependency Graph Visualization

Feature: Rule Dependency Graphs (Visualization)

Objective:
Implement a feature that visualizes rule dependency graphs in the RulesEngine administration portal and/or API. This will help users understand how rules and workflows interconnect, making it easier to debug, optimize, and maintain complex rule sets.

Requirements:

• Analyze and extract rule dependencies from workflow definitions (e.g., rules referencing outputs of other rules).
• Generate a directed graph model representing these dependencies.
• Provide a backend API endpoint to retrieve dependency graphs for a given workflow version (e.g., as a JSON structure compatible with common graph libraries such as Cytoscape.js, D3.js, or Mermaid).
• (Frontend) Integrate a visualization component (e.g., D3.js, Cytoscape.js, or Mermaid) that consumes the backend graph and displays it interactively.
• Highlight potential issues: cycles, unreachable rules, or orphan rules.
• Optionally: Allow users to navigate from the graph to rule definitions for quick editing.

Acceptance Criteria:

• Backend exposes a dependency graph API for each workflow version.
• Admin UI displays the graph for any workflow.
• Cycles, orphans, and unreachable nodes are visually distinguished.
• Documentation updated for this feature.

• RulesEngine Wiki
• Cytoscape.js
• Mermaid

Start by reading the workflow definitions and the RulesEngine Wiki to understand how rule outputs express dependencies. Review the administration portal and API entry points, then define the graph response and visualization approach. Done means each workflow version exposes a graph, the admin UI distinguishes cycles, orphan rules, and unreachable rules, and the documentation is updated.
