Communities of Nations Bridged by Language Similarity

Different clusters of languages are prominent in different nations of the world. You can therefore "connect" nations based on the similarity of their set of prominent languages. This Demonstration visualizes this connection. The left panel of the graphic shows the connections among the nations based on whether they satisfy a user-specified level of "Jaccard similarity" among their prominent languages. The right panel shows a disconnected graph in which a high proportion of the links are intra-community.
