# Heroku Buildpack: Graphviz

Install [Graphviz](http://www.graphviz.org/) on Heroku.

## Description

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

The installed version of Graphviz depends on the Heroku stack (which is automatically detected by the buildpack):

- [Heroku-22](https://devcenter.heroku.com/articles/heroku-22-stack) → [Graphviz 2.42.2](https://packages.ubuntu.com/jammy/graphviz)

- [Heroku-20](https://devcenter.heroku.com/articles/heroku-20-stack) → [Graphviz 2.42.2](https://packages.ubuntu.com/focal/graphviz)

- [Heroku-18](https://devcenter.heroku.com/articles/heroku-18-stack) → [Graphviz 2.40.1](https://packages.ubuntu.com/bionic/graphviz)

The Graphviz executables are installed to the following directory:

```

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

```

The above directory is added to the `PATH` environment variable, so Graphviz commands like `dot` and `neato` are directly available to your app without specifying their path.

## Install

For adding the buildpack in addition with other buildpacks, use:

```bash

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

```

For setting the buildpack as the only buildpack, use:

```bash

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

```

You can verify that the buildpack has been added with:

```bash

heroku buildpacks

```

## Verify

After deploying your application with the buildpack at least once, you can verify the installation of Graphviz with:

```bash

heroku run dot -V

```

The above command runs `dot -V` on the application dyno, that is, in the same environment in which your application is running. That means, if the above command succeeds, your application can use Graphviz commands such as `dot` in the same way.
