  Monitoring communities has become increasingly easy on the web as the number
of visualisation tools and amount of data available about communities increase.
It is possible to visualise connections on social and professional networks
such as Facebook in the form of mathematical graphs. It is also possible to
visualise connections between authors of papers. In particular, Microsoft
Academic Search now has a large corpus of information on publications, together
with author and citation information, that can be visualised in a number of
ways. In mathematical circles, the concept of the "Erd\H{o}s number" has been
introduced, in honour of the Hungarian mathematician Paul Erd\H{o}s, measuring
the "collaborative distance" of a person away from Erd\H{o}s through links by
co-author. Similar metrics have been proposed in other fields, including
acting. The possibility of exploring and visualising such links in arts fields
is proposed in this paper.
