“Generally, the table displays the form of involvement of certain companies in respective arms deliveries. Thus, every row of the table shows a different form of involvement and not necessarily a different arms delivery.”
The colums are definitions like "company involvement" or "Contribution to Delivery", but these categories are constructed and can be questioned - what is involvement, what is a contribution?
weapons sold are grouped into the rows
States are measured with GPS locations and displayed on a map
The hierarchy of companies involved in selling arms is not transparent, this would need a seperate dataset.
