You should install GraphViz on your system first.

Use this in Ubuntu:

sudo apt-get install graphviz

Sometimes you may need additional packages like in Fedora you should also install graphviz-gd to be able to export images, like this:

# dot, svg and postscript work without graphviz-gd but png, jpeg and gif don't
sudo dnf install graphviz graphviz-gd
