# Technical Document Analysis of Line Chart
## Chart Description
The image is a line chart comparing the accuracy (%) of four models (GSM8K, ASDiv-Aug, MultiArith, SVAMP) across 12 layers. The chart lacks a title but includes axis labels, a legend, and data points.

### **Axis Labels and Markers**
- **X-axis**: "Layer Index" (values: 1, 2, 3, 6, 8, 10, 12)
- **Y-axis**: "Accuracy (%)" (range: 0–80, increments of 10)

### **Legend**
- **Location**: Bottom-left corner
- **Labels and Colors**:
- **GSM8K**: Blue (dashed line)
- **ASDiv-Aug**: Purple (solid line)
- **MultiArith**: Orange (dotted line)
- **SVAMP**: Green (dash-dotted line)

- **Key Points**:
- Layer 1: ~32%
- Layer 3: ~31%
- Layer 6: ~32%
- Layer 12: ~33%
2. **ASDiv-Aug (Purple)**
- **Trend**: Peaks at Layer 8, then declines.
- **Key Points**:
- Layer 1: ~68%
- Layer 3: ~66%
- Layer 6: ~69%
- Layer 8: ~70%
- Layer 12: ~62%
3. **MultiArith (Orange)**
- **Trend**: Sharp peak at Layer 8, followed by a decline.
- **Key Points**:
- Layer 1: ~70%
- Layer 3: ~62%
- Layer 6: ~67%
- Layer 8: ~72%
- Layer 12: ~64%
4. **SVAMP (Green)**
- **Trend**: Relatively flat with minor fluctuations.

### **Spatial Grounding**
- **Legend Position**: Bottom-left corner (confirmed via visual alignment).
- **Color Consistency**:
- Blue (GSM8K) matches dashed line.
- Purple (ASDiv-Aug) matches solid line.
- Orange (MultiArith) matches dotted line.
- Green (SVAMP) matches dash-dotted line.
---
### **Critical Observations**
- **ASDiv-Aug** and **MultiArith** show the highest variability, with ASDiv-Aug peaking at Layer 8 and MultiArith peaking at Layer 8 before declining.
- **SVAMP** maintains the most stable performance across layers.
- **GSM8K** exhibits the least variability but remains the lowest-performing model.

### **Conclusion**
The chart provides a clear comparison of model accuracy across layers. No textual data tables or non-English content are present. All labels, axis markers, and legend entries are explicitly extracted and cross-verified for accuracy.
