# Technical Document Analysis: Line Chart
## Chart Type
- **Line Chart** with multiple data series plotted against a grid background.
## Axes
- **X-Axis (Horizontal)**:
- Label: `Model Number`
- Range: 1 to 22 (discrete ticks at every integer)
- Tick Interval: 1 unit
- **Y-Axis (Vertical)**:
- Label: `Score (%)`
- Range: 0 to 100
- Tick Interval: 20 units
## Legend
- **Location**: Top-right corner of the chart
- **Color-Label Mapping**:
- **Cyan**: `Tau2-bench Telecom`
- **Gold**: `Tau2-bench Retail`
- **Green**: `Tau-bench Retail`
- **Pink**: `Tau2-bench Airline`

## Spatial Grounding
- **Legend Position**: Top-right quadrant (coordinates: [x=19, y=95] relative to chart bounds).
- **Data Point Verification**:
- All line colors match legend labels (e.g., cyan = `Tau2-bench Telecom`).
## Notes
- The chart emphasizes performance trends across model iterations for different benchmarks.
- `ComplexFuncBench` is explicitly called out at Model 14 but lacks a full data series.
- No textual data tables or heatmaps present; all information is encoded in line plots.
## Transcribed Text (Non-English)
- No non-English text detected in the image.
