Installation issue

Javascript and npm are not my regular tools, so sorry if this is trivial...

From macOS Sonoma 14.3 following the installation, in a python activated environment containing OAK and then running, e.g.:
`runoak -i ubergraph: viz CL:4023094`
would give
`/bin/sh: dot: command not found`
Running
`which og2dot`
gave
`SomePath/.nvm/versions/node/v22.9.0/bin/og2dot`

In the end, somehow magically solved by running (being on mac) `brew install graphviz`

Start by checking the installation instructions and package configuration for the `runoak` command and its Graphviz `dot` dependency. Verify the reported macOS installation path and determine whether a fresh installation documents or provides the required dependency; done means the installation behavior or instructions clearly prevent this error.
