It is undocumented, likely on purpose. It was added a few versions back as
a way to test the charts outside the confines of an iFrame, with the
eventual goal of switching the default behavior to not use iFrames (set to
occur next release). Some time in the future, the option will be removed
entirely. If everything goes smoothly, the process will be entirely
transparent to developers and users. I suggest using the option merely as
a means around an inconvenience (that is, it is mildly annoying to get at
the contents of an iFrame).
