# Technical Document Extraction: Bias Detection Threshold Chart
## 1. Document Metadata
* **Title:** Bias Detection Threshold
* **Chart Type:** Vertical Bar Chart with a Threshold Line
* **Language:** English
## 2. Component Isolation
### A. Header
* **Text:** "Bias Detection Threshold" (Centered at the top).
### B. Main Chart Area (Axes and Data)
* **Y-Axis Label:** "Max Confidence Level (1-α)"
* **Y-Axis Scale:** Linear, ranging from 0.0 to 1.0 with major tick marks every 0.2 units (0.0, 0.2, 0.4, 0.6, 0.8, 1.0).
* **X-Axis Label:** "Node"
* **X-Axis Categories:** Non-sequential integers representing specific nodes: 2, 3, 6, 7, 9, 10.
* **Threshold Line:** A horizontal dashed red line is positioned at $y = 0.8$.
### C. Legend/Visual Indicators
* **Data Series:** Blue bars representing the confidence level for each node.
* **Reference Line:** Red dashed line representing the "Bias Detection Threshold."
## 3. Data Extraction and Trend Verification
### Trend Analysis
The data shows a non-linear distribution across the selected nodes. The confidence levels are low for the initial nodes (2 and 3), rise significantly to a peak at Node 7, and then decline through Node 10. Only one node (Node 7) exceeds the defined threshold of 0.8.
### Data Table Reconstruction
The following table represents the approximate values extracted from the visual height of the blue bars relative to the Y-axis markers.
| Node (X-Axis) | Max Confidence Level (Y-Axis) | Status Relative to Threshold (0.8) |
| :--- | :--- | :--- |
| 2 | ~0.10 | Below |
| 3 | ~0.10 | Below |
| 6 | ~0.40 | Below |
| 7 | ~0.90 | **Above** |
| 9 | ~0.70 | Below |
| 10 | ~0.20 | Below |
## 4. Key Findings and Observations
* **Threshold Breach:** Node 7 is the only component that surpasses the Bias Detection Threshold, reaching a confidence level of approximately 0.9.
* **Near-Threshold:** Node 9 shows a high confidence level (~0.7) but remains below the 0.8 detection limit.
* **Baseline Nodes:** Nodes 2 and 3 show the lowest confidence levels, both sitting at approximately 0.1.
* **Gaps in Data:** The X-axis is not continuous (missing nodes 1, 4, 5, and 8), suggesting this chart focuses on a specific subset of nodes under investigation.
