Documentation related to visualization methods

[abhi-glitchhg]

I have added some fixes for page breaks in #86.

Still, we need to enhance the docs for visualization methods.
We can include the license/copyright disclaimer for visualization methods in our license or have a separate file.

Additionally, we can add the sample outputs from these methods into the doc.

We definitely need to improve our documentation, not just for visualization, but overall. Having tutorials would help. Maybe we can have a tutorial for these viz methods and include a sample output in it.
