Conventional citation analysis typically focuses on distinctive members of a specialty — the cream of the crop. Landscape visualizations naturally emphasize the peaks rather than the valleys. Such practices remind us of either the Matthew Effect or the winner-takes-it-all phenomenon. However, scientific frontiers are constantly changing. We cannot simply ignore the “root” of the crop or the valleys of an intellectual landscape. Today’s valleys may become tomorrow’s peaks.
