Thematic community network of diabetes drug research in greater China. This figure consists of 14 communities which are shown as nodes and labelled by their high frequency keywords in which italic words are research topics more relevant to a given community than to the others and those letters in bold are more related to Chinese medicines. Community size increases with number of articles, and edge thickness between any two nodes corresponds to the frequency of co-publications involving authors from those two communities. These subnetworks are labelled in descending order of number of institutes
