Bear in mind, this HTML was generated by running the clustering algorithm on my specific computer — your installed fonts will be different if you check this out on a non-Ubuntu machine. In fact, if you don’t have ALL of Ubuntu’s font packages installed, you may see a lot of fonts that look the same; your system is switching to a default font.
On the other hand, if you have access to an Ubuntu machine, you’ll be able to experiment with the sample text, its size, and colors.
I will try to get access to a Mac so that I can do some final checks on the code. The next hurdle will be trying to get Python modules installed in a Windows machine.
