Fig. 7: Histogram of compositional layout within each spatial grid across different sources (Source: created by the authors).

In each panel, the x axis represents the ten fundamental compositional components, and the y axis denotes the number of images in which each component appears within the corresponding grid position. The four datasets are consistently color-coded: HAG_D (red), HAG_T (orange), SP_D (green), and SP_T (blue). The figure consists of nine panels corresponding to the spatial grid positions defined by the rule-of-thirds framework: a top-left, b top-center, c top-right, d middle-left, e middle-center, f middle-right, g bottom-left, h bottom-center, and i bottom-right. Each panel illustrates the distribution of components within its respective grid position.
