# Technical Document Extraction: Bar Chart Analysis
## Chart Overview
The image is a **grouped bar chart** comparing the performance of three algorithms across nine datasets. The chart uses **DQN-normalized scores** as the metric, with scores ranging from 0 to 8 on the y-axis. The x-axis lists nine datasets, and the legend identifies three algorithms via color coding.

### **Key Trends and Data Points**
1. **DT-Mem (Yellow Bars)**:
- Consistently achieves the **highest scores** across all datasets.
- Notable peaks:
- **Kangaroo**: ~6.5
- **Qbert**: ~6.8
- **SeaQuest**: ~6.2
- **NameThisGame**: ~6.7
2. **RMDT (Orange Bars)**:
- Moderate performance, generally **mid-range scores**.
- Notable dips:
- **RoadRunner**: ~2.5 (lowest RMDT score)
- **Phoenix**: ~5.8
3. **MDT (Blue Bars)**:
- Highly variable performance.
- Notable peaks:
- **SeaQuest**: ~7.0 (highest MDT score)
- Notable dips:
- **Kangaroo**: ~2.3 (lowest MDT score)
- **Phoenix**: ~3.8

### **Spatial Grounding and Color Verification**
- **Legend Alignment**:
- Orange bars (RMDT) match the legend’s orange label.
- Yellow bars (DT-Mem) match the legend’s yellow label.
- Blue bars (MDT) match the legend’s blue label.
- **Dataset-Specific Observations**:
- **Kangaroo**:
- RMDT: ~5.0
- DT-Mem: ~6.5
- MDT: ~2.3
- **SeaQuest**:
- RMDT: ~4.3
- DT-Mem: ~5.5
- MDT: ~7.0
- **RoadRunner**:
- RMDT: ~2.5 (lowest)
- DT-Mem: ~6.3
- MDT: ~4.6
---
### **Trend Verification**
- **DT-Mem**: Slopes upward consistently across datasets, maintaining dominance.
- **RMDT**: Fluctuates but remains mid-range, with a sharp drop in RoadRunner.
- **MDT**: Erratic trend, with a peak at SeaQuest and a trough at Kangaroo.

### **Conclusion**
The chart highlights **DT-Mem** as the most robust algorithm, while **MDT** shows situational superiority (e.g., SeaQuest). **RMDT** underperforms in RoadRunner but remains stable otherwise. No textual data tables or non-English content are present.
