It's been solved more than once actually --- Red Hat did a "Visual
Explain" tool several years ago, which is unmaintained now but still
available for download (http://sources.redhat.com/rhdb/). I've heard
that EDB picked it up and is now maintaining their own fork, but I
don't know the status of that for sure. That code is in Java, if it
makes a difference to you.
