Fig. 3.

2D visualization of the age generation-based face preference networks. Nodes represent the 90 faces. Edges represent symmetrical, binary relations between nodes. Colors represent face age (younger, red; middle-aged, green; older, blue). Shapes represent face sex (female, ellipse; male, round rectangle). Labels denote face sex and age (F1, younger female face; M1, younger male face; F2, middle-aged female face; M2, middle-aged male face; F3, older female face; M3, older male face).
