Install Graphviz - All Platforms

[Back To MAIN Modular Emacs README]

Introduction:

Harmonic Alchemy Modular Emacs comes integrated with the popular Graphviz utility which allows the creation of nice graphs, flowcharts, data diagrams, etc. using a powerful scripting language called dot... The Emacs mode for Graphviz is: graphviz-dot-mode Graphviz is a very old and useful program (almost as old as Emacs itself!) that has been supported by package managers for ages! You should have no problem installing Graphviz...

Modular Emacs invokes: graphviz-dot-mode when you visit files ending in either: .dot or .gv

When you are visiting a .dot file, you can compile it with C-c C-C which will produce a .svg file along side... By default, Modular Emacs produces SVG vector files (instead of .png files)... which is my preference because if you add one to a markdown file and then view it using VMD-Mode you can expand the resulting rendered chart or graph full screen and it will still look very sharp! Not to mention you can edit the resulting SVG file within inkscape to add things to it that Graphviz cannot... Don't underestimate the power of Graphviz though! Read the docs!

You could create a nice workflow that starts programmatically within some program or language, invoke graphviz to produce some diagrams, export to SVG, then edit the resulting .svg in inkscape to add some fancy graphics or other things, Lastly import the final .svg into Blender to add animations, 3D, etc... The sky is the limit!

Note: You better send me an email to show me the cool thing you made on Github after reading this! :octocat:

Install Graphviz on Mac OS:

You have 2 options: HomeBrew, or MacPorts... (building from source is not necessary)

  • MacPorts: - Install Graphviz: V2.40.1_2 (as of this writing)
 $_  sudo port install graphviz   # To install it...
 $_  port echo requested          # To see it in the list 
                                  # of installed packages.
  • If you use Homebrew, do this instead:
 $_  brew install graphviz

That's it... Easy Peasy! :octocat:

Install Graphviz on Linux:

Graphviz is in the Debian, Ubuntu, Slackware, Arch, Fedora, NiXOS, openSUSE, and gentoo repositories so you don't have to build this one either. ;-)

  • Debian, Ubuntu flavors:
 $_  sudo apt install graphviz
  • RedHat, Fedora flavors:
 $_  sudo dnf install graphviz

That's it... Easy Peasy! :octocat:
