Is anyone out there aware of any cool little tools or applications that make it easy to build a graphically stimulating website map? Ive seen Visio and a few others but I cant believe there isnt something out there that I can simply type the first, second and third level page names and have it render a nice diagram in flash of the exact site map and allow me to view it perfectly. If its not out there then why cant we just build it ourselves then?
