Usage is pretty simple.

# Get a instance of the API (while passing in your apikey)
api = PyAptgraph('wKJtkVQ3QXoUJW5hryrFXRXDEoJhiwFmvA2KEWMSNH3AcMMPsx')

# Add a couple of random values to this graph, then send it to Aptgraph
# Note that 8jspy is this graphs id.
api.add('8jspy', random.randint(1,100))
api.add('8jspy', random.randint(1,100))
api.send()
