Thanks, would using a topological sort or other simpler algos, not sufficed processing the graph with cycles directly, may not be as optimised as Pregel, but would have been simpler.
Langgraph engineer seems promising, especially given the complexity in building an effective agentic AI solution. While Pragel seems like an overkill (to build graphs on internally in langgraph), not found other simpler tools that provide same flexibility to build and visualize agent based flows.
Looking for similar tools for a project am working on.
