- No error handling
- Incorrect counts due to including headers

**After:**
- Fixed ranges to exclude headers (B2:B50, D2:D50, E2:E50)

  - X-axis: Schadensausmaß (Gering, Mittel, Erheblich, Schwer, Katastrophal)
  - Y-axis: Eintrittswahrscheinlichkeit (Sehr gering, Gering, Mittel, Hoch, Sehr hoch)
  - Risk scores: 1-25 (probability × severity mapping)
  
- **Color-Coded Cells:**
  - Green (1-5): Akzeptabel
  - Yellow (6-10): Tolerabel
  - Orange (11-15): Undesirable
  - Red (16-25): Intolerable

   - Format: 0.0% (one decimal place)

2. **Risk Distribution by Hazard Type:**
   - Formulas to count hazards by type using COUNTIF
   - Displayed in chart helper cells (A15:B19)

3. **Average Risk Level Calculation:**
   - Formula: `AVERAGE(Risikobewertung!F2:F50)`
   - Displays average risk score across all hazards
   - Format: 0.0 (one decimal place)

**Benefits:**
- Deeper insights into risk distribution
- Percentage-based metrics for better understanding
- Average risk level for overall assessment

### 6. Assessment Date Tracking
