Description: Map of upstream service dependencies for a specific service and operation

APM Overview dashboard offered by Promscale on top of traces by leveraging SQL and TimescaleDB capabilities.

This dashboard contains:

1. **Map of Upstream Dependencies**  representing nodes and edges here nodes are services and edges are connections between services. This panel represents all upstream dependencies for the selected service and operation.
