Interpretation
In this network, every node is a country. Countries are connected if they co-appear significantly in the webpages of the aid organizations' websites. The nodes are colored accordingly to the region of the world where the country is.
From the network, we can observe that nodes tend to be tightly connected more with other nodes of the same color. This means that, for international organizations, countries are significantly related to each other mainly because they are in the same world region.
