Network Map Generator

I'm looking for a product or script that will let us generate a network map for use in conjunction with Nagios. We have all of the parent/child dependencies defined in a SQL table, as well as the current status, but I can only find programs that will create a live map on my desktop. I also looked at the graphing Pear module, but it seems that it cannot generate an org-chart type map of the network. Anyone know of something that will generate an org-chart like network map dynamically? Sincerely, Joe Johnson joe@sendjoeanemail.com
