Have they included a network mapping function yet? They announced it as a GSoC project last year I think, did they get around to hack some graphical map output?
Good question--and yes, we have! Full details on this feature, including screen shots, are provided in Section 12.5, "Surfing the Network Topology" starting on page 317. That section is also available free online. The code has been integrated into the latest version (4.76) of Nmap, available here.
