# Scan specific project
gcp-radar inventory --project my-project --export inventory.csv

# Export to specific region
gcp-radar inventory --region us-central1 --export inventory.csv

2. Generate Architecture Diagram

gcp-radar diagram --input inventory.csv --output architecture.drawio

# Then open architecture.drawio in app.diagrams.net or the desktop app

3. One-Shot: Scan + Diagram

gcp-radar run --project my-project \
  --output-csv inventory.csv \
  --output-diagram architecture.drawio
