The University of Adelaide has an interesting site: The Internet Topology Zoo. Its a collection of visualizations, tools, and data sets for visualizing internet service providers. These visualizations have been all gussied up- by properly placing nodes on maps, but other data sets used in tools such as Cytoscape or Gephi will not only visualize but analyze large networks.
I would love to recreate the snapshot of the internet created by M. Newman in May 2006 with current data to determine such metrics as closeness or betweeness of GW's autonomous system.
Hi - the datasets are all available as GML or GraphML which you can use for analysis, or to attempt to reconstruct the Internet.
