Ubiquitination in diabetes and its complications: A perspective from bibliometrics

Figure 7 Visualization of keywords in diabetes ubiquitination studies. A: Visualization of the co-occurrence analysis of keywords in diabetes ubiquitination research. Only keywords with a frequency of 6 or more occurrences are shown. Each node represents a keyword, and the size of the node is proportional to its frequency. The thickness of the connecting lines indicates how frequently two keywords co-occur, and different colors represent the years the keywords appeared; B: Timeline visualization of the top ten keywords clustering analysis. Keywords on the same line correspond to the clusters on the right. Each node represents a keyword, and the size of the node is proportional to its frequency. The position of the node on the horizontal axis indicates the keyword's first occurrence; C: Timeline visualization of keywords. Each node represents a keyword, and its size is proportional to the frequency of the keyword. The position of the node on the horizontal axis indicates the time of the keyword's first appearance.
