As internet usage has grown, so too have the various online networks which connect family, friends, colleagues and people with shared interests. Whilst it is often easy to gain a numerical overview of connections, friends or followers, this tends to add context, rather than insight – the fact remains, it can be difficult to dig that bit deeper and see how people within networks are linked. This poses a challenge for digital communicators as we want to tap into big, social data and visualise networks; so we can see how ideas may spread, understand who knows whom and identity people that are influential within a particular context. After all, if you can understand a network, you gain insight into who people may trust, find influential and credible.
