The image presents a network visualization of authors and key phrases associated with sustainability research. Text elements appear in different font sizes, where larger words represent higher relevance or frequency. The layout is non-linear, with names and phrases positioned irregularly across the space. The phrase Transforming our world: the twenty appears centrally and in the largest font, indicating high significance. Other names and phrases are scattered around it, suggesting thematic relationships without directional flow. A background gradient subtly differentiates areas but does not imply strict clusters.Density map of co-cited articles
