Figure 5
The polar area chart is drawn as a circular diagram divided into labeled segments around the perimeter, showing three stages: “Primary stage” on the upper right, “Intermediate stage” on the lower right, and “Advanced stage” on the left. The outer circular axis is labeled sequentially with categories “P1” through “P9”, “I1” through “I9”, and “A1” through “A9”. A color legend at the bottom left reads “Color Legend: P1 to P9: Red (Primary); I1 to I9: Blue (Intermediate); A1 to A9: Green (Advanced)”. In the “Primary stage” red segments from P1 to P9, the values are labeled as follows: P1: 0.3958, P2: 0.0868, P3: 0.0834, P4: 0.0865, P5: 0.0827, P6: 0.0781, P7: 0.0773, P8: 0.0713, and P9: 0.0381. Among these, P1 shows the largest radial extent. In the “Intermediate stage” blue segments from I1 to I9, the values are: I1: 0.347, I2: 0.0974, I3: 0.0945, I4: 0.089, I5: 0.0863, I6: 0.0861, I7: 0.086, I8: 0.0838, and I9: 0.0298. The largest value appears at I1. In the “Advanced stage” green segments from A1 to A9, the values are: A1: 0.3073, A2: 0.1139, A3: 0.0957, A4: 0.0926, A5: 0.0921, A6: 0.0903, A7: 0.0853, A8: 0.0808, and A9: 0.0419. The highest value is at A1. The radial grid is marked with concentric circles labeled approximately 0.1, 0.2, 0.3, and 0.4, indicating magnitude from the center outward. The colored filled wedges extend outward from the center to their respective values, forming three grouped distributions for Primary, Intermediate, and Advanced stages.Radar chart of factors' weights.
