Is there an existing front-end package that can read the output of the user stats and display it in a more user-friendly format? Essentially, something reads the JSON output from http://solo.ckpool.org/users/1Xabc123whatever and converts it into a pretty table or grid or something, so that the user can monitor performance.

I could write up something like this, but I'd rather not reinvent the wheel if there's something already existing.  However, there wasn't anything listed in the first couple of pages that I saw, and a Google search didn't find anything useful.
