I think you're right, that the HathiTrust pie chart has far too many slices to be useful, and it would make me happier if when you clicked on one piece of the pie you got another pie showing the subdivisions within, e.g., the history of Asia, rather than just a full list of the tens of thousands of books on the history of Asia. But for the project I have in mind -- providing access to a much smaller collection of digitized historical material -- I think something like the pie chart could work well (although probably not using LCC to create the slices). At least, it would help give the user some perspective on what topics are covered in said historical collection. From the undergraduates I see, one of the biggest problems they have is getting a sense of the shape of the scholarly landscape in general, and of what's in a given database in particular. "I only get 3 results when I search for my topic! Am I doing it wrong, and there's a whole lot of stuff out there I'm not finding? Is there nothing on anything even remotely close to my topic, and I should give up and choose a different topic? What topics in this area ARE viable?" That frustration seems to go double for archival materials (a less familiar concept with a less familiar organizational system). I think making it easy for students to get a rough sense of that landscape would be really helpful, and there's no tool like a visual tool for getting a quick impression of the lay of the land.
