Feature: Rule Dependency Graph Visualization

[Loynova-Meena]

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.
