## Line Graph: Test Loss vs Depth
### Overview
The image is a line graph comparing test loss across six datasets (Wikipedia, Books, Internet Books, Common Crawl, WebText2 (Train), WebText2 (Test)) at three depth levels (10¹, 10², 10³). The y-axis represents test loss (2.3–2.8), and the x-axis represents depth on a logarithmic scale. Each dataset is represented by a distinct colored line.

### Detailed Analysis
1. **WebText2 (Train)** (purple):
- **Trend**: Flat line with minimal fluctuation.
- **Values**:
- 10¹: ~2.35
- 10²: ~2.32
- 10³: ~2.33
- **Observation**: Consistently the lowest test loss across all depths.
2. **WebText2 (Test)** (brown):
- **Trend**: Slightly upward slope.
- **Values**:
- 10¹: ~2.42
- 10²: ~2.38
- 10³: ~2.40
- **Observation**: Slightly higher than WebText2 (Train), with a minor increase at 10³.
3. **Common Crawl** (red):
- **Trend**: Slightly downward slope.
- **Values**:
- 10¹: ~2.52
- 10²: ~2.47
- 10³: ~2.48
- **Observation**: Higher than WebText2 datasets but lower than others.
4. **Internet Books** (green):
- **Trend**: U-shaped curve (peak at 10¹, dip at 10², rise at 10³).
- **Values**:
- 10¹: ~2.75
- 10²: ~2.68
- 10³: ~2.72
- **Observation**: Highest loss at 10¹, improving at 10², then worsening at 10³.
5. **Books** (orange):
- **Trend**: Relatively flat with minor fluctuations.
- **Values**:
- 10¹: ~2.82
- 10²: ~2.78
- 10³: ~2.80
- **Observation**: Highest test loss across all datasets.
6. **Wikipedia** (blue):
- **Trend**: Slightly downward slope.
- **Values**:
- 10¹: ~2.72
- 10²: ~2.68
- 10³: ~2.70
- **Observation**: Moderate loss, improving slightly with depth.
