# Command: graph
The `terraform graph` command is used to generate a visual
representation of either a configuration or execution plan.

## Usage
core: graph command gets -verbose and -draw-cycles When you specify `-verbose` you'll get the whole graph of operations, which gives a better idea of the operations terraform performs and in what order. The DOT graph is now generated with a small internal library instead of simple string building. This allows us to ensure the graph generation is as consistent as possible, among other benefits. We set `newrank = true` in the graph, which I've found does just as good a job organizing things visually as manually attempting to rank the nodes based on depth. This also fixes `-module-depth`, which was broken post-AST refector. Modules are now expanded into subgraphs with labels and borders. We have yet to regain the plan graphing functionality, so I removed that from the docs for now. Finally, if `-draw-cycles` is added, extra colored edges will be drawn to indicate the path of any cycles detected in the graph. A notable implementation change included here is that {Reverse,}DepthFirstWalk has been made deterministic. (Before it was dependent on `map` ordering.) This turned out to be unnecessary to gain determinism in the final DOT-level implementation, but it seemed a desirable enough of a property that I left it in.

Outputs the visual dependency graph of Terraform resources according to
configuration files in DIR (or the current directory if omitted).
The graph is outputted in DOT format. The typical program that can
read this format is GraphViz, but many web services are also available
to read this format.

* `-draw-cycles` - Highlight any cycles in the graph with colored edges.
This helps when diagnosing cycle errors.

* `-module-depth=n` - The maximum depth to expand modules. By default this is
command: Change module-depth default to -1 This means that terraform commands like `plan`, `apply`, `show`, and `graph` will expand all modules by default. While modules-as-black-boxes is still very true in the conceptual design of modules, feedback on this behavior has consistently suggested that users would prefer to see more verbose output by default. The `-module-depth` flag and env var are retained to allow output to be optionally limited / summarized by these commands.

-1, which will expand all modules.

for potential operations in place.

## Generating Images
The output of `terraform graph` is in the DOT format, which can
easily be converted to an image by making use of `dot` provided
by GraphViz:
```
$ terraform graph | dot -Tpng > graph.png
```
Here is an example graph output:
