File o directory non esistente: 'dot': 'dot'

Thanks for your job. But I'm trying model graph (Odoo v.12) and I got always this error: Error: Odoo Server Error

Traceback (most recent call last): File "/home/odoo/.local/lib/python3.6/site-packages/pydot.py", line 1878, in create stderr=subprocess.PIPE, stdout=subprocess.PIPE) File "/usr/lib/python3.6/subprocess.py", line 709, in init restore_signals, start_new_session) File "/usr/lib/python3.6/subprocess.py", line 1344, in _execute_child raise child_exception_type(errno_num, err_msg, err_filename) FileNotFoundError: [Errno 2] File o directory non esistente: 'dot': 'dot'

During handling of the above exception, another exception occurred:
