UK repositories : growth of records

For a while now I’ve been running a weekly script which connects to ROAR and grabs the number of records for each UK based Institutional Repository. I’ve finally got around to writing a web front end to this, which you can see here. All quite basic at the moment, and I have lots of ideas of what I could do to improve this (one idea based on the compare average number of deposits per repository). Have a look and let me know what you think, and let me know of any bugs.
