Figure 5
The scatter plot titled “K-Medoids Clustering of Papers (k equals 12)” is drawn on a coordinate plane. The horizontal axis is labeled “U M A P 1” and ranges from 13 to 19 in increments of 1 unit. The vertical axis is labeled “U M A P 2” and ranges from 4 to 9 in increments of 1 unit. The plot contains multiple data points grouped into 12 clusters, each represented by a distinct color. A vertical color bar legend on the right side is labeled “Cluster” and shows values from 0 to 10 in increments of 2. The data points are distributed across the plane forming visible clusters. A dense cluster appears in the lower-left region around (14, 5). Another cluster is located in the upper-left region around (15, 8). A large cluster appears on the right side between (18, 7) and (19, 7.5). Several clusters are concentrated in the central region around (16, 7) and (17, 8). Additional smaller clusters appear near (17, 5), (16.5, 4.8), and (18, 5.5). A compact cluster is visible near the top center around (16.5, 9). The clusters are separated spatially but partially overlap in the central region. Points within each cluster are closely grouped, while different clusters occupy distinct regions across the U M A P space. Note: All numerical data values are approximated.K-medoids clustering of selected literature. This scatterplot shows the twelve clusters identified by applying k-medoids clustering to the papers included in the scoping review. Each point represents one paper, and the colors indicate cluster membership. The x- and y-axes (UMAP 1 and UMAP 2) represent low-dimensional projections of the label information used to describe the papers. Source: Authors’ own work
