# Technical Document: Bar Chart Analysis
## Chart Description
This image is a **stacked bar chart** comparing the performance of two AI models, **Nano Banana Pro** and **Seedream 4.5**, across nine safety categories. The chart evaluates the percentage distribution of responses classified as **Refusal**, **Unsafe**, and **Safe** for each category. The x-axis lists the categories, while the y-axis represents percentages (0–100%). The legend is positioned on the right, with color-coded segments and model-specific patterns.
### Key Components
1. **Axes**:
- **X-axis**: Categories (`Disturbing`, `Hate`, `Humiliation`, `Illegal Activity`, `IP`, `Public Figures`, `Sexual`, `Violence`, `Average`).
- **Y-axis**: Percentage (%) from 0 to 100.
2. **Legend**:
- **Colors**:
- **Gray**: Refusal
- **Red**: Unsafe
- **Blue**: Safe
- **Patterns**:
- **Nano Banana Pro**: Striped bars
- **Seedream 4.5**: Solid bars
3. **Data Representation**:
- Each category has two stacked bars (one per model), divided into three segments (Refusal, Unsafe, Safe).
