# Technical Document Extraction: Line Chart Analysis
## Chart Overview
The image is a **line chart** comparing the performance of two models, **DT-Mem** and **MDT**, across varying numbers of model parameters. The y-axis represents **Human-Normalized IQM Score** (percentage), and the x-axis represents **Number of Model Parameters** (in millions).

## Axis Labels and Markers
- **X-Axis (Horizontal):**
- Title: *"Number of Model Parameters"*
- Markers: `10M`, `12M`, `20M`, `40M`, `50M`, `200M`
- **Y-Axis (Vertical):**
- Title: *"Human-Normalized IQM Score"*
- Range: `0%` to `160%` (in increments of `20%`)

## Legend
- **Location:** Top of the chart
- **Labels and Colors:**
- `DT-Mem` (Blue line)
- `MDT` (Orange line)

## Data Points and Trends
### DT-Mem (Blue Line)
- **Trend:** Steep upward slope, with a sharp increase between `10M` and `20M` parameters, followed by a slower rise.
- **Data Points:**
- `10M`: `26%`
- `12M`: `71%`
- `20M`: `123%`
- `40M`: `143%`
- **Note:** The line extends beyond `40M` but no explicit value is provided for `50M` or `200M`.
### MDT (Orange Line)
- **Trend:** Gradual upward slope, with consistent growth across all parameter ranges.
- **Data Points:**
- `10M`: `56%`
- `12M`: `71%`
- `20M`: `93%`
- `40M`: `126%`
- **Note:** The line extends to `200M` but no explicit value is provided.

## Key Observations
1. **DT-Mem** outperforms **MDT** at all parameter levels, with a significantly higher IQM score at `20M` (`123%` vs. `93%`).
2. Both models show diminishing returns as parameters increase beyond `20M`, though DT-Mem maintains a higher score.
3. The chart does not include data for parameters beyond `40M` for either model, despite the x-axis extending to `200M`.

## Spatial Grounding and Validation
- **Legend Placement:** Top-center, matching the color of the lines (blue for DT-Mem, orange for MDT).
- **Data Point Validation:**
- Blue line (DT-Mem) matches the legend color and trends.
- Orange line (MDT) matches the legend color and trends.

## Conclusion
The chart illustrates that **DT-Mem** achieves higher human-normalized IQM scores than **MDT** across all tested parameter ranges, with a more pronounced improvement at lower parameter counts. No additional textual or numerical data is present in the image.
