How to install graphviz on mac with homebrew? (2023)

How do I get Graphviz on my Mac?

Homebrew is a free and open-source software package management system that simplifies the installation of software on Apple's operating system, macOS, as well as Linux. The name is intended to suggest the idea of building software on the Mac depending on the user's taste.

Run "dot -V" from the command prompt. If GraphViz is installed and configured you'll get it's version.

Homebrew fills the void as the de facto package manager for macOS (and as another option for Linux). It provides an incredibly smooth and straightforward experience for anyone familiar with the command line, and it's a good way to learn the command line if you're new to it.

Homebrew on its own acts like a command-line App Store. It's safe, if you know what you're downloading. It uses SHA256 to fingerprint the downloaded instructions as a validity / tamper detection verification check. It's open, so you could validate what it's downloading and how it works.

Mac M1 (Apple silicon)

Homebrew supports the Mac M1 chip (Apple silicon) beginning with the release of Homebrew 3.0. 0 in February 2021. On Apple silicon, Homebrew installs files into the /opt/homebrew/ folder, which is not part of the default shell $PATH .

Providing path to Graphviz

If you've installed Graphviz and pip is unable to find Graphviz, then you need to provide pip with the path(s) where it can find Graphviz. To do this, you first need to figure out where the binary files, includes files, and library files for Graphviz are located on your file system.

How do I run Graphviz in Python?

To install the graphviz Python package, you can use pip : conda install pip and pip install graphviz . Always prefer conda packages if they are available over pip packages. Search for the package you need ( conda search pkgxy ) and then install it ( conda install pkgxy ).

PIP is automatically installed with Python 2.7. 9+ and Python 3.4+ and it comes with the virtualenv and pyvenv virtual environments.

Graphviz on Windows

In Advance settings, a dialogue box opens that shows the Environment Variables button. Click the button. Select the entry Path in the system variables section and add C:\Program Files (x86)\GraphvizX. XX\bin to the existing path.

But if you install Homebrew on an M1 Mac running Apple Silicon, then Homebrew gets installed in /opt/homebrew/bin . Since /opt/homebrew/bin is not included in your PATH by default, there is some extra configuration needed to allow you to use packages installed with Homebrew.

The Z shell (also known as zsh ) is a Unix shell that is built on top of bash (the default shell for macOS) with additional features. It's recommended to use zsh over bash . It's also highly recommended to install a framework with zsh as it makes dealing with configuration, plugins and themes a lot nicer.

Dot e, x, e, is an extension at the end of a filename in DOS based system architecture (i.e. Windows) that means 'executable'. Dot e, x, e, files are used to tell the operating system to start a program or application.

Graphviz (short for Graph Visualization Software) is a package of open-source tools initiated by AT&T Labs Research for drawing graphs specified in DOT language scripts having the file name extension "gv". It also provides libraries for software applications to use the tools.

What is Pydot in Python?

Pydot is a Python library, also written in Python, that "serves as a graphical interface to Graphviz, an open source graph visualization software. GraphViz is written in DOT language, but Pydot provides the ability to parse and dump data, between Python and DOT."[

brew cask is an extension to brew that allows management of graphical applications through the Cask project. Homebrew Cask extends Homebrew and brings its elegance, simplicity, and speed to OS X applications and large binaries alike. Cask deals with a mixture of software and licences.

EDIT: Seems like the consensus and my research as shown that Homebrew (not many people chimed in about Mac Ports) seems relatively trust worthy and safe/secure.

For those developing on macOS - pressing down Command + Shift + Period (Command + Shift + .)

Create a graph object, assemble the graph by adding nodes and edges, and retrieve its DOT source code string. Save the source code to a file and render it with the Graphviz installation of your system. Use the view option/method to directly inspect the resulting (PDF, PNG, SVG, etc.) file with its default application.
