Why do I get an error when changing the engine? Everything works fine with the dot engine.

Code: 

from graphviz import Graph

dot = Graph()
dot.engine = 'neato'

dot.node('a')
dot.node('b')

dot.edge('a', 'b')

print(dot.source)
dot.render('test-output/round-table.gv', view=True)

Error:

graphviz.backend.ExecutableNotFound: failed to execute 
['neato', '-Tpdf', '-O', 'test-output/round-table.gv'], 
make sure the Graphviz executables are on your systems' PATH

this helped me to resolve the problem on windows:
"RuntimeError: Make sure the Graphviz executables are on your system's path" after installing Graphviz 2.38
installed from https://graphviz.gitlab.io/_pages/Download/Download_windows.html using .msi, manually added to PATH.
if you're using jupyter notebook, do restart your cmd window and probably web browser
