Using Views relationships with Slickgrid

Drupal newbie here, so advance apologies for my illiteracy and naivete.

Issue. I want to configure a slickgrid view that displays values from two
different content types using some kind of relation.

Context. I have two content types: Specimens and Locations. Specimen nodes
are related to Location nodes using 'Location ID' as a node reference.
Currently, the Slickgrid View for Specimens displays the Location ID for each
specimen (e.g. 'loc1, loc2, loc3, etc.). What I want is for the other
values of the Location content type (e.g. Country, State, City, etc.) to
also be displayed. That way, instead of just seeing that 'Specimen X' was
collected from 'Loc1', I can also see that it was collected fromUSA,
California, San Francisco.
Thanks!
