According to bill you posted:

Number of Pages: 217 Number of Total Words: 65396 Number of Unique Words: 3106 You will know 90% of words after 28 pages which are 12.90% of the book. At that page, you will know 36.77% of unique words.

The graph is less regular but it has more or less same shape. I will not publish this part because it is not a book.

Actually,

I do have a requested challenge for you: US laws.

Can you evaluate this law that just was signed 3 days ago:

http://leginfo.legislature.ca.gov/faces/billTextClient.xhtml...

(There is a link to a PDF of the law if you prefer to DL the PDF first...)

That is bit different analysis, but I will. Ping me on @r_kierzkowski on twitter, so we will stay in touch.

Can you plot his most used to least used, please.
