The base map was created from citation patterns among a set of over 7,000 scientific journals. The profile for NIH was calculated by matching the principal investigators and their institutions from grants funded in 1999 to first authors and their institutions on papers indexed in 2002. Colored nodes show the distribution and numbers of papers linked to grants; red nodes indicate faster moving science than yellow nodes; colored edges show linkages in the NIH funding profile that are stronger than the corresponding linkages in the base map of science.
