Dynamic evolution of research impact across disciplines. Corresponding to each data period—2007–2012 (a), 2009–2014 (b) and 2011–2016 (c)—the Science Landscape diagrams are shown. The figures on the left show the top views and the figures on the right show the birds-eye views. The eight ‘base’ research areas are arranged along the edge of the circular map, and the angle allocated to each research area is proportional to the number of papers from each discipline. The highest and lowest levels of research impact are depicted in red and blue, respectively
