Network visualizer

It's a built-in tool in Oracle Cloud Infrastructure's Console that gives you a graphical, topology-based map of your cloud network — VCNs, subnets, gateways, peering connections, load balancers, and their interconnections — all rendered visually in real time without needing to write a single query.

Key uses:

1. Quickly audit your entire network layout across compartments
2. Troubleshoot connectivity issues by visually tracing paths
3. Validate routing rules and security list configurations
4. Onboard new team members by showing them the actual environment, not documentation

Benefits:

1. No extra cost — it's native to OCI Console
2. Real-time topology reflects your live infrastructure
3. Clickable nodes drill into resource details instantly
4. Great for multi-VCN and hub-and-spoke architectures
