The horizontal axis has two markings: the first marking on the far left represents the year 2022, and the second marking toward the far right represents the year 2024. The vertical axis is labeled “Term” and shows different topics arranged from top to bottom as follows: “green human resource management,” “green innovation,” “circular economy,” “sustainability,” “circular economy practices,” and “corporate social responsibility.” The chart uses bubbles positioned along the horizontal axis.
