ImportError: No module named ImageFont

I'm using the chemlab library for the first time. I'm trying to run some of the example programs but I keep getting the following error message:

import ImageFont # From PIL

ImportError: No module named ImageFont

Here is the code to one of the basic examples (https://github.com/chemlab/chemlab/blob/master/examples/nacl.py):

from chemlab.core import Atom, Molecule, crystal
from chemlab.graphics import display_system

# Molecule templates
na = Molecule([Atom('Na', [0.0, 0.0, 0.0])])
cl = Molecule([Atom('Cl', [0.0, 0.0, 0.0])])

s = crystal([[0.0, 0.0, 0.0], [0.5, 0.5, 0.5]], # Fractional Positions
            [na, cl], # Molecules
            225, # Space Group
            cellpar = [.54, .54, .54, 90, 90, 90], # unit cell parameters
            repetitions = [5, 5, 5]) # unit cell repetitions in each direction

display_system(s)

I've tried installing ImageFont, PIL and Pillow via pip (Pillow was the only one that actually installed) but no luck.

Install PIL:

pip install pillow

Correct import for ImageFont is:

from PIL import ImageFont

Here is an example of ImageFont:

from PIL import ImageFont, ImageDraw

draw = ImageDraw.Draw(image)

# use a bitmap font
font = ImageFont.load("arial.pil")

draw.text((10, 10), "hello", font=font)

# use a truetype font
font = ImageFont.truetype("arial.ttf", 15)

draw.text((10, 25), "world", font=font)
