What problem does it solve?
This Skill eliminates the guesswork and common pitfalls of designing data visualizations and dashboards that fail to communicate insights, are inaccessible to users with disabilities, or underperform in production, ensuring every chart answers a specific business question effectively.
Core Features & Use Cases
- Question-aligned chart selection: Uses a decision tree rooted in the question the chart needs to answer, not just data shape, to pick the optimal chart type and avoid anti-patterns like pie charts with too many slices or dual y-axes.
- Production-ready guidance: Includes library trade-offs for Recharts, D3, Plotly and others, dashboard layout heuristics for executive and analyst use cases, color-blind safe palette recommendations, and specifications for loading, empty, and error states.
- Accessibility and performance compliance: Built-in rules for screen reader support, keyboard navigation, SVG/Canvas rendering thresholds, and color contrast to meet accessibility standards out of the box.
Use case: A SaaS product team building a user analytics dashboard can use this Skill to select the optimal chart for tracking monthly active user growth, define a layout that lets executives extract key insights in 5 seconds, and specify implementation details including color-blind safe palettes and error states that frontend engineers can implement without additional design input.
