- Title and Conclusion slides should be visually distinct or offer special design instructions.
|
||||
- Content slides must follow a logical and clear structure.
|
||||
|
||||
3. **Content Density Control**:
|
||||
- Each slide must contain **3–6 concise bullet points**.
|
||||
- Each point should be **no more than 50 characters**.
|
||||
- Distribute content evenly across slides to avoid overload or redundancy.
|
||||
|
||||
4. **Chart Suggestions**:
|
||||
- For any data, comparisons, or visual-friendly content, suggest a chart and include its configuration under `chart_config`.
|
||||
- Specify chart type (e.g., bar, pie, line), provide sample data, and chart options.
|
||||
|
||||
5. **Language & Tone**:
|
||||
- The entire outline should be in **{language}** and aligned with the communication preferences of the target audience.
