I execute the sample code, but there is an error problem. ` [root@ flowchart]# python3 analyzer.py -s sample.py -v interesting_variable -a list-append Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/graphviz/backend.py", line 164, in run proc = subprocess.Popen(cmd, startupinfo=get_startupinfo(), **kwargs) File "/usr/lib64/python3.6/subprocess.py", line 709, in init restore_signals, start_new_session) File "/usr/lib64/python3.6/subprocess.py", line 1344, 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:

This is old, but make sure you have GraphViz on your system
