Yes it does.  Personally, I don't find a single prefix visualization
helpful, as it will mostly duplicate the general AS propagation graph. It
might be interesting if it could do "compare AS graphs for prefix FOO and
BAR" or something like that, but generally you are going to do that muh
quicker on a CLI or with grep/awk fu.
