+- Supports multiple data sources (e.g., CloudWatch, Prometheus, etc.)
+
+## Usage
+```hcl
+module "managed_grafana" {
+  source = "terraform-aws-modules/managed-service-grafana/aws"
+
+  name                      = "${var.environment_name}-grafana"
+  description               = "AWS Managed Grafana service ${var.environment_name} environment."
+  account_access_type       = "CURRENT_ACCOUNT"
+  authentication_providers  = ["AWS_SSO"]
+  permission_type           = "SERVICE_MANAGED"
+  data_sources              = var.data_sources
+  notification_destinations = ["SNS"]
+
+  workspace_api_keys = {
+    viewer = {
+      key_name        = "viewer"
+      key_role        = "VIEWER"
+      seconds_to_live = 3600
+    }
+    editor = {
