How photos spread virally through Facebook

Three videos on Facebook Stories from Stamen Design visualise how photos posted by George Takei were shared and re-shared over time. Stamen’s work is always wonderful — this is remarkable.

There’s no rubric, but I’m assuming that this is a form of network graph — where each node may itself become the source of new edges.

What’s interesting, if that’s the case, is how only a few shares lead to huge bursty cascades of sharing. I’ve seen this before on much smaller data sets:

There’s a potentially useful paper, The Dynamics of Viral Marketing, (Leskovec et al., 2007) that addresses this phenomenon. I’d be grateful for links to other papers — or your thoughts.
