The data was analysed using the software VOSviewer - http://www.vosviewer.com/ free software for visualising networks. Differences in colours represents, the clusters of publications with those authors picked out by the software. The relative size of the circles is the relative number of publications listed; so for the two biggest circles/hubs it relates to 55 and 34 publications in this time period. Some relatively new authors, to the University but not to research, explains some of the 'islands' and the number of publications within it - it only reflects publications whilst at the University of Northampton.
To dig a little deeper, going to look at the two biggest 'hubs' through their NECTAR records, so potentially going back before 2010.

The line thicknesses reflect the amount of collaboration (papers) between authors. My personal views it shows a mixture of working with some key co-authors, as well as also working with wider sets of authors is a positive strategy.
All views and opinions are the author's and do not necessarily reflected those of any organisation they are associated with. Twitter: @scottturneruon
