Hi Alex and Klaus,
Thank you for the respond, and yes I made it using NS_VIS_ASSIGN.
So the simulation only takes the details of link specification right?
Finally got it done,
Thank You again, Alex and Klaus
Best Regards,
Adi Paramartha

Technically, the data does contain the name of each router's city +
state/country. So one could do a geolocation lookup and visualize the
routers based on that :)
However, it's not very fine-grained, so many routers will share the same
city.
Best regards,
Klaus
