I got this idea from seing a visualization in a book. Make a list of all the books on my shelf. For each book find the amazon page it is on For each amazon book page extract the “Customers Who Bought This Item Also Bought” links and information (title, author) For each Also bought link, extract those “Customer Who Bought This Item Also Bought” Links” Put it into a json object for the the top level book an graph it with d3.js
