Broken links to Nexus in documentation #438
Description
Report from the forum about broken links in the tutorial:
In igraph and the outside world, both links referring to the Zachary karate club study and igraph’s own graph repository called Nexus are broken.
As an exercise, download the graph representation of the well-known Zachary karate club study from igraph’s own graph repository called Nexus, unzip it and try to load it into igraph .
Nexus is no longer available so these should be removed.
