I would recommend that you put the text you get back from the URL in a file (just now, for testing purposes), so you can experiment with various transforms on it. When you have the raw data in a text file, you can take advantage of your editor's color-coding to see what is what in the raw string.

You're going to have to read through the data and figure out how it works, so you can understand what parts are data and what parts are the callback functions. Read about JSONP and what it is and how and why you would use it. Until you truly understand what the developers have been doing in order to construct their page, you won't know how to pare back the page-building parts and get just the raw data out of the payload.

Once you have done this, though, the very last step (parsing the data with the standard library JSON function) will be a trivial maraschino cherry on top of the sundae.

Until you actually understand the data, you cannot scrape it or parse it. So eat your vegetables first!
