Installing GraphViz on MacOS

I wanted to test Command: graph | Terraform | HashiCorp Developer by cd-ing to an arbitrary Terraform module and executing:

% terraform graph -type=plan | dot -Tpng >graph.png

But this issued an error:

zsh: command not found: dot

Solution:

% brew install graphviz  
...
==> Installing graphviz
==> Pouring graphviz--9.0.0.arm64_ventura.bottle.tar.gz
🍺  /opt/homebrew/Cellar/graphviz/9.0.0: 287 files, 7.1MB
==> Running `brew cleanup graphviz`...
Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.
Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).

To verify installation:

% dot --version 

dot - graphviz version 9.0.0 (20230911.1827)
