Planning Phase: System Architecture Design

Design a LangGraph architecture for a multi-agent system focused on AI data center investment analysis. Outline the core agents required (e.g., Market Researcher, Financial Analyst, Regulatory Compliance Agent, Infrastructure Planner, Decision Agent), their specific roles, and the state transitions within your graph. Describe how these agents will communicate and collaborate to perform a comprehensive ROI and risk assessment. Specify which information each agent will contribute to the shared state.
