This script generates topology graphs of traceroute data of a particular region/group of countries in the Guthrie database. You need to provide either the name of the traceroute server that you will use to do the traceroute or specify a file containing the raw traceroutes. In the absence of thes these arguments the program does traceroutes from the current machine.
Visualizing topology graphs can be very useful for seeing and demonstrating how direct or indirect routing is between countries (often routing between countries close to one another in developing regions can go via Europe or the US). It is also useful to discover hosts whose location is not properly known.
