AS paths in hypviewer
Here are some views of AS paths in hypviewer. The displayed spanning tree represents AS connectivity according to AS paths in BGP as seen from pinot.caida.org on March 3, 1999. The AS path data was collected using mrtd. Note that I removed the sphere from these pictures for clarity; after using hypviewer for a while, the sphere becomes clutter that you don't need.
