About the Nagios Map

i read on the nagios book that you can drag the host on the status map… is it possible? how can i do that? coz ive configured 2nd coord of 500+ host and there;s more and im tired of configuring it… can anyone teach me how to drag the host on the status map?.. coz my boss wants a circular but not a nagios circular so i configured 2nd coordinates. and i heard about nagvis i thinks kinda hard to install using Putty…

thx in advance
