The horizontal axis is labeled “P C 1” and has markings ranging from negative 3 to 3 in increments of 1 unit. The vertical axis is labeled “P C 2” and has markings ranging from negative 4 to 5 in increments of 1 unit. The axes intersect at the center to form 4 quadrants. The plot includes five groups represented by different symbols and colors. “P S (Proactive Seekers)” is represented by square markers in gray, positioned on the upper left and lower left quadrants. “D Q (Disenchanted Quitters)” is represented by asterisk markers in grey, positioned on the upper left and lower left quadrants. “F I (Fast Integrators)” is represented by X markers in gray, positioned on the lower right quadrant. “L B (Late Bloomers)” is represented by diamond-shaped markers in black, positioned on the lower right quadrant. “I L (Inertial Learners)” is represented by circular markers in grey, positioned on the upper left and upper right quadrants.Biplot of key factors separating language trajectory clusters.
