It's a step in the right direction, but it took a very long time to load on my computer.
After the initial load, it was pretty peppy, then I ran the default example that is grayed in but not active (I had to retype it) Then I get the page that says "results are ready" and how cool they are, then it takes me a while to figure out what I am looking at and finally realize it is a comparison of data quality metrics (which I think are all fact counts) between all of the P31 predicates and the Q5. The use of the graphic on the first row complicated this for me. There are a lot of broken links on this page too such as http://tools.wmflabs.org/wd-analyst/sitelink.php https://www.wikidata.org/wiki/P31 and of course no merged in documentation about what P31 and Q5 are. Opaque identifiers are necessary for your project, but Also some way to find the P's and Q's hooked up to this would be most welcome. It's a great start and is completely in the right direction but it could take many sprints of improvement.
