+## 7. View the application connections
+
+Radius connections are more than just environment variables and configuration. You can also access the "application graph" and understand the connections within your application with the following command:
+
+```bash
+rad app connections
+```
+
+You should see the following output, detailing the connections between the `demo` container and the `db` Redis Cache, along with information about the underlying Kubernetes resources running the app:
+
+```
+Displaying application: demo
+
+Name: demo (Applications.Core/containers)
+Connections:
+  demo -> db (Applications.Datastores/redisCaches)
+Resources:
+  demo (kubernetes: apps/Deployment)

 It's easy to build on the default app and add more resources to the app.
