Heroku Buildpack: Graphviz

Install Graphviz on Heroku.

Description

This buildpack installs Graphviz on and makes it available to your Heroku application.

The installed version of Graphviz is:

Graphviz 2.42.2 for the Heroku-20 stack
Graphviz 2.40.1 for the Heroku-18 stack
Graphviz 2.38.0 for the Heroku-16 stack

The Graphviz executables are installed to the following directory (from where they are available to your app):

/app/.heroku-buildpack-graphviz/usr/bin

The buildpack also adds this directory to the PATH, so your app can directly use the Graphviz executables (like dot and neato) as simple commands.

Enable

Add the buildpack in addition to other buildpacks:

heroku buildpacks:add https://github.com/weibeld/heroku-buildpack-graphviz

Or set the buildpack as the only buildpack:

heroku buildpacks:set https://github.com/weibeld/heroku-buildpack-graphviz

Verify

After running the buildpack, you can verify the installation of Graphviz with:

heroku run dot -V
