This visualization gives an overview of the whole citation network. The colors represent the four main groups of journals, which are further subdivided into fields in the outer ring. The segments of the inner ring represent the individual journals, scaled by Eigenfactor™ Score. In the initial view, the top 1000 citation links are plotted. Line size and opacity represents connection strength.

The lines in the centre of the circle remind me of threads of cotton. This links nicely to the cotton mills built in Ancoats during the Industrial Revolution.
