Issue with graph-pdf command

[kohlsudduth]

Hello! Thank you so much for sharing this very useful program. I'm running into an issue with graph-pdf command. I've included the error message from terminal below. I'm using The Archive. As I'm a CLI neophyte, most likely this is user error. Could you please advise? Thank you for your fine work.

$ python3 --version Python 3.7.7 $ vizel graph-pdf /Users/kohl/Dropbox/zettelkasten/ Traceback (most recent call last): File "/usr/local/lib/python3.7/site-packages/graphviz/backend.py", line 159, in run proc = subprocess.Popen(cmd, startupinfo=get_startupinfo(), **kwargs) File "/usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Versions/3.7/lib/python3.7/subprocess.py", line 800, in init restore_signals, start_new_session) File "/usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Versions/3.7/lib/python3.7/subprocess.py", line 1551, in _execute_child raise child_exception_type(errno_num, err_msg, err_filename) FileNotFoundError: [Errno 2] No such file or directory: 'dot': 'dot'

During handling of the above exception, another exception occurred:

Hey @kohled, thanks for giving vizel a try and reaching out. It looks like you're on a mac. You need to install graphviz on the system as well. The easiest way to do this is with brew install graphviz.

I'll add this to the documentation.

Do the other commands work?

Dang. Thought I'd checked that graphviz was installed. Thanks for the help.

Yes all other commands work great.

Putting this fine program to immediate daily use. Really appreciate your work.
