This dub packages enables you to call python coding from D. In 
this specific case functions from the python module 
matplotlib.pyplot.

The dub package calls this python file which causes your error as 
python cannot find matplotlib.pyplot.

https://github.com/koji-kojiro/matplotlib-d/blob/master/python/prebuild.py

Therefore python needs to be installed and also matplotlib.pyplot.

I got the dub package example working some weeks ago. In general 
it should work.

Kind regards
