This tutorial shows how to import the discrete transporation events from a Pajek file and visualize the events. Documentation on the Pajek format is available at Importing a Pajek Graph. The import of transportation data of beef for Austria is used as an example here.

The Pajek File

The following text must be copied into a new textfile named graph.net. In the Vertices* section node references are specified for AT-2, AT-3, ... AT-10. These are nodes from the STEM library graph of Austria. In the Edges* section migration edges between these nodes are defined. The edges have default migration rate of zero and a rate >0 for a specified date. That means only a this date beef moves from one region to another.
