File "C:\Users\constantinos\AppData\Local\Programs\Python\Python37-32\lib\site-packages\graphviz\files.py", line 188, in render
rendered = backend.render(self._engine, format, filepath, renderer, formatter)
File "C:\Users\constantinos\AppData\Local\Programs\Python\Python37-32\lib\site-packages\graphviz\backend.py", line 183, in render
run(cmd, capture_output=True, check=True, quiet=quiet)
File "C:\Users\constantinos\AppData\Local\Programs\Python\Python37-32\lib\site-packages\graphviz\backend.py", line 150, in run
raise ExecutableNotFound(cmd)
graphviz.backend.ExecutableNotFound: failed to execute ['dot', '-Tpdf', '-O', 'iris'], make sure the Graphviz executables are on your systems' PATH

as the error suggests, you must install Graphviz and add it your system PATH. Specific steps depend on your system, you can easily find the answers to these online — Anton

You have to install graphviz for this to work, not just the Python package, but also the binary distribution.

See https://www.graphviz.org/

Then you have to put the path to dot in your PATH environment variable.

You have graphviz installed? Then you didn't set PATH properly. It needs to point to the folder where dot.exe is.
