Figure 3
The image contains a three-field plot that combines a vertical bar graph, a line graph, and a keyword cloud. The plot is divided into three sections labeled CR, AU, and KW_Merged. The CR section on the left lists cited references with their respective authors and publication years. The AU section in the middle shows authors with lines connecting to the cited references. The KW_Merged section on the right displays keywords with lines connecting to both the cited references and authors. The vertical axis of the CR section lists references with their authors and years, while the horizontal axis of the AU section lists authors. The KW_Merged section has a vertical axis listing keywords. The lines indicate the relationships between cited references, authors, and keywords. Keywords such as article, sustainability, human, and sustainable development are prominently displayed. Three-field plot of cited references, authors and keywords
