The `url` field specifies the URL of the Prometheus server to fetch the metrics from. In this case, the URL is `http://prometheus:9090`.

The `isDefault` field specifies whether the data source is the default data source in Grafana.
 
 Apart from the services, the Docker Compose file also defines a volume named `grafana-data` to persist the Grafana data and a network named `go-network` to connect the services together. You have created a custom network `go-network` to connect the services together. The `driver: bridge` field specifies the network driver to use for the network.
