Data Visualization

• Recommends the right chart type based on what you're trying to show (trends, comparisons, distributions, relationships)
• Applies design principles that make charts clear and easy to read (proper labels, colors, and minimal decoration)
• Ensures visualizations are accessible to all audiences including colorblind users
• Guides responsive design so charts work on mobile and desktop
• Provides best practices for direct labeling, context, and interactive exploration

Heuristic Evaluation

• Evaluates your interface against 10 proven usability heuristics like system visibility, error prevention, and consistency
• Documents each issue with severity ratings from cosmetic to critical
• Provides specific recommendations for fixing each problem found
• Reviews both new user and experienced user perspectives
• Prioritizes findings so you know what to fix first
