title: How to store data from Google Ngram API?
body: <p>I need to store the data presented in the graphs on the Google Ngram website. For example, I want to store the occurences of "it's" as a percentage from 1800-2008, as presented in the following link: <a href="https://books.google.com/ngrams/graph?content=it%27s&amp;year_start=1800&amp;year_end=2008&amp;corpus=0&amp;smoothing=3&amp;share=&amp;direct_url=t1%3B%2Cit%27s%3B%2Cc0" rel="nofollow">https://books.google.com/ngrams/graph?content=it%27s&amp;year_start=1800&amp;year_end=2008&amp;corpus=0&amp;smoothing=3&amp;share=&amp;direct_url=t1%3B%2Cit%27s%3B%2Cc0</a>.</p>
  
  <p>The data I want is the data you're able to scroll over on the graph. How can I extract this for about 140 different terms (e.g. "it's", "they're", "she's", etc.)?</p>
