To draw a network you have first to define it. Assume that the
50,000 titles are vertices, what are the links?
Some years ago I wrote a program in Python to get the network from
Amazon based on "Customers who bought" ...
Since the program was interrupted several times I built in also
the 'restart from' option.
For small networks (some houndreds of vertices) I wrote, as an
'how to' illustration for students, a similar program in R.
The structure of Amazon's pages changed - some adaptations in both
programs are needed.
