# Technical Document Extraction: Bar Chart Analysis
## Image Description
The image is a **bar chart** visualizing the relationship between **question difficulty** (x-axis) and the **average number of <thinking> tokens** (y-axis). Three data series are represented using distinct colors:
- **1B** (blue)
- **3B** (red)
- **8B** (green)
The chart includes a legend in the **top-left corner** and axis labels for both x and y axes.

## Data Table Reconstruction
| Question Difficulty | 1B | 3B | 8B |
|---------------------|------|------|------|
| 0 | 5.2 | 3.8 | 6.2 |
| 1 | 5.5 | 4.4 | 6.8 |
| 2 | 5.9 | 4.6 | 7.2 |
| 3 | 5.7 | 4.5 | 7.4 |
| 4 | 5.9 | 4.7 | 7.4 |
| 5 | 5.6 | 4.9 | 7.8 |

## Observations
1. **1B (Blue)** shows a **non-linear trend**, peaking at difficulty 2 before declining slightly.
2. **3B (Red)** exhibits a **consistent upward trend** across all difficulty levels.
3. **8B (Green)** demonstrates the **strongest positive correlation** between question difficulty and token count, with a **steady increase** from 6.2 to 7.8.

## Notes
- The chart does not include a title or additional textual annotations beyond axis labels and legend.
- All data points align with the legend colors (blue = 1B, red = 3B, green = 8B).
- No other languages or textual elements are present in the image.
