Graphical Site Map Tool?

Does anyone know of a program to analyze and display graphically, a websites structure/hierarchy???

Years ago there was a site manager tool bundled with Softquad's Hot Metal Pro. You gave it the index page of a site and it created a 'tree' of all the pages showing all the connections between pages.

I've searched the web and this is all i've found so far....

None of these are floating my boat
