Lancet - color by age or publications (2000-2023)

The map shows 13391 publications. The classification underlying the map is based on 20 million PubMed publications from 1995 onwards and their citation relations (NIH Open Citation Collection).
  Top level nodes (large, partly transparant nodes) represent research disciplines. Small nodes with solid color represent research specialties.
  Clicking on a discipline will show the closest related disciplines as well as the specialties within the discipline. Clicking on a specialty will show the closest related specialties as well as the parent discipline. The panel to the right shows attributes for the clicked node as well as a list of underlying clusters (topics if clicking a specialty and specialties if clicking a discipline).
