Which command generates DOT formatted data for visualizing dependencies in Terraform?

The command that generates DOT formatted data for visualizing dependencies in Terraform is "terraform graph." This command creates a graph of all the resources defined in your configuration, as well as their dependencies. The resulting output is in the DOT format, which can be used with Graphviz – a graph visualization software – to create visual representations of the resource dependencies.

When you run "terraform graph," Terraform analyzes the plan and outputs a directed graph that represents the relationships between resources. This can be particularly useful for understanding complex infrastructures as it allows you to quickly identify how different components are interlinked.

The other options do not serve this function: "terraform visualize" is not a valid command in Terraform, "terraform format" is used to format Terraform configuration files according to canonical style, and "terraform dependencies" unlike the graph command, doesn't exist as a specific command in the Terraform CLI. Hence, "terraform graph" is clearly the correct choice for generating a DOT formatted output for visualizing dependencies.
