Design Principles
- Clarity: Remove chart junk, maximize data-ink ratio
- Accuracy: No distortion, appropriate scales
- Efficiency: Quick comprehension, key insights prominent
- Actionability: Clear implications for decisions
- Accessibility: Color-blind friendly, alt text provided
Best Practices
- Match visualization type to data and message
- Use consistent color schemes across related charts
- Include clear titles and axis labels
- Highlight key takeaways with annotations
- Provide interactive features for exploration
- Export to multiple formats for different uses
- Include data tables for accessibility
Integration Points
- Receives data from all analysis skills
