A few years ago The Guardian posted some Desert Island Discs data on their datablog. After a bit of cleaning up (typos, ambiguous band names etc) I’ve extracted distinct castaways and artists and turned them into graph files. One file has artists as nodes and castaways as edges, the other vice-versa.
Probably doesn’t reveal a lot, but was an interesting exercise.
The GML files can be opened by most graph analysis software (Mathematica, Gephi etc) and can be found here:
