Graphviz's executables are not found (Python 3.4)

To solve this problem,when you install graphviz2.38 successfully, then add your PATH variable to system path.Under System Variables you can click on Path and then clicked Edit and added ;C:\Program Files (x86)\Graphviz2.38\bin to the end of the string and saved.After that,restart your pythonIDE like spyper,then it works well.

Don't forget to close Spyder and then restart.
